Triathlon Training: The Ultimate Beginners' Guide

Welcome to the exciting world of triathlons!

Although the triathlon is a challenging endurance sport, you don’t have to be fast, or even want to go fast, to get value out of participating in a triathlon event. If you’re trying to win a race or push your boundaries as an athlete, the triathlon can be a great tool. But if you’re just looking for a new way to have fun and stay fit, that’s great too.  

Either way, if you want to enjoy the experience, proper triathlon training is a must. 

The combined rigors of swimming, biking and running will draw on a higher degree of strength and conditioning than required by each individual discipline. Though the training process does not have to consume your life to be enjoyable and rewarding, the triathlon can demand a strong dedication to all aspects of fitness — physical, mental and emotional — from training through successful completion of race events.  

Fortunately, the commitment it takes to finish a triathlon makes the accomplishment that much more thrilling. That feeling of achievement is why the triathlon is often described as “addictive.”  So consider yourself warned: you may not want to quit after your first race.  

We’ve got a lot to cover here, so either follow along for the whole swim, ride and run, or use the following menu to skip from section to section: 

Triathlon Events & Distances

Although you can certainly swim, bike and run as much as you want on your own, the sport of triathlon usually centers around organised large-scale events, with each athlete responsible for their own training.  

As a beginner, you’ll want to choose an event to register for, then build your triathlon training plan to suit your race length, terrain and environment, as well as how far away it is.  

Both total distance and relative distance of each leg can vary by event, but you can expect the swim portion to be the shortest, the bike to be the longest, and the run to fall somewhere in between.  

The most common event and distance options include: 

Most athletes find success by starting with the Sprint triathlon distance and working their way up.  

How to Approach Your Triathlon Training Plan 

Triathlon training is different for beginners than habitual triathletes or serious competitors. In addition to being able to handle a higher volume of training, veterans of the sport often train based on seasons, racing multiple events in the course of a training cycle.  

You may eventually get to that point, but most beginners will find it easier to approach training for a triathlon the same way we approach our first running, cycling or swimming events — by training just for that event. 

Your ideal beginner triathlon training plan should be focused on a clear understanding of your goals. These can be short-term, long-term or overarching. Before deciding for yourself what results to focus on to get you up and going when that alarm clock goes off at early o’clock, ask yourself a few questions:  

After an honest appraisal of the above issues, you’ll be able to set a series of goals (short and long term) that’ll help you find the ideal intensity level for your training and focus on desired results throughout your training process. 

For example, your goals might look like the following:

Regardless of what results you’re hoping to get out of the triathlon training process, each training-to-event cycle has a singular aim: to be at your peak on race day. 

Can I Do Triathlon Training in the Gym?

While there are pros and cons for both indoor and outdoor workouts in preparation for triathlons, realistically, you’ll benefit from using both.  

Typically, gym-based workouts will be more useful in the early phases of a triathlon training plan, where goals are more generalised to the task of building a base level of fitness. Controlled indoor environments such as pools, stationary bikes and treadmills add scheduling convenience and allow you to track progress with fewer variables. 

As workouts progress and race day approaches, training should move outdoors with increasing exclusivity to get better prepared for conditions you’ll face during a triathlon. During the middle of a race is no time to make a first-ever adjustment to adverse weather, low visibility or temperature changes. 

Make sure you review additional considerations affecting your training timeline, as well as each phase of the race — especially any leg you have less experience with. Access to a gym environment, outdoor venues and routes, or even the eventual race route can all be invaluable to training.  

For safety purposes, please note that swimming in a controlled pool environment (with a floor and walls) can require substantially less physical effort than a similar distance in a natural body of water.

Swim Training for Triathlon 

If you’re a triathlon beginner without prior exposure to competitive and distance swimming, welcome to one of the most demanding yet invigorating sports around.   

The swim is always the shortest leg of a triathlon. Why?  For one, it takes more energy to move a human body through water relative to the bike and run portions of a race. That’s because swimming involves more resistance and greater coordination of contributions from the entire body.  Breathing is also a lot easier on land.  

For these reasons (and as a safety precaution), the swim is also the first portion of any triathlon. So the training you do in the pool and open water to boost performance in this leg will set the tone for the rest of the event on race day.  

The eventual goal of swim training is to build a foundation that allows you to proceed through the swim leg of a triathlon at a steady, sustainable pace without overexerting yourself. Getting there will involve a blend of general conditioning and endurance training, specific distance swimming training and a focus on developing a fundamentally sound, efficient stroke. 

Joining a group, whether formal or not, is a great way to train for any leg of the triathlon. If you’re not the most confident swimmer, some guided instruction is a must. And especially with regard to swimming, it’s always safer not to train alone. 

Swim Training for Triathlon: Equipment

Swimming doesn’t require much equipment, but most triathlons prohibit skinnydipping.

As a general rule for all phases of the triathlon, training equipment should resemble eventual race gear as closely as possible. As far as the swim is concerned, you may wish to purchase duplicates after settling on a preferred option.

Train more exclusively in actual race equipment to gain comfort, confidence and familiarity as race day approaches. Race day should not be the first time you use or wear any given piece of equipment.

Consult specific race rules for details on allowable specs for swim suits, caps, goggles, wetsuits and accessories. Often, race rules governing swimming gear will be based on the standards laid out in the British Triathlon Competition Rules.

Swim Training for Triathlon: Technique 

Although technically allowed under race rules, the dog paddle is incredibly inefficient. 

If you’ve never learned the details of front crawl stroke from a coach with a background in competitive swimming, you’ll want to get at least an informal stroke clinic session as early as possible in any triathlon training, with additional sessions for evaluation as you progress. 

You should also explore more formal coaching if you find yourself struggling with any of the following technique issues commonly faced by less experienced swimmers: 

• Inability to establish a regular breathing rhythm, including excessive or regular water up the nose 
• Difficulty timing breathing in-stroke, so that each breath causes a hitch or pause in swimming motion 
• Lack of comfort swimming with head down, face forward but submerged, or difficulty transitioning fluently into or out of a heads-up position used for sighting the next buoy or marker 
• Unnecessary lateral movement, and/or difficulty holding a straight line  
• Excessive splashing, exertion, or any irregular stroke feature that pushes the body backwards through the water 

An efficient swimming stroke should have the following qualities: 

• A straight axis maintained through the center line of the body, pointing directly ahead at all times 
• Flutter kicking with bend at the hips but legs as straight as possible, including pointed toes — especially avoiding scissor kicking or excessive knee bend that could add resistance or skew the center line 
• Downstrokes that pull through the water with palms facing downward for as long as possible, fingers rigid but not unduly spread apart and pointed toward the centerline, as if hoisting one’s self onto a ledge 
• Arms exiting the water on each upstroke with elbows high, bringing each hand up to the top of the stroke in a hand-raising motion rather than a jumping jack motion, and knifing the hand back into the water comfortably at either an eleven or one o’clock position on a watch dial without overreaching 
• Breathing down and to the side in rhythm, moving the chin to meet the armpit of the upstroke hand, and facing forward again as the arm passes 
• Raising the head for sighting in rhythm with the upstroke 

Before starting a training schedule, familiarise yourself with specific race rules for details on swimming conduct, and train accordingly. Often, race rules governing swimming conduct will be based on those set out under the British Triathlon Competition Rules.

Swim Training for Triathlon: Guidance and Structure 

Out of all the ways to get ready to swim in a triathlon, one should be avoided: The John Wayne Method.  

It’s much better to get expert help than it is to attempt a sink-or-swim approach. 

Regardless of your level of comfort with self-guided swim training, you’ll benefit from a structured lesson or practice group arrangement, especially one with a focus on triathlon training.  

Evaluate training group options near you, and make sure to share your goals and race — including distance, location, expected water temperature and required equipment — with your coach or group leader. They should be able to cater a series of swimming workouts, drills and sets to help you build toward your target distance. 

For experienced swimmers who are new to triathlon, self-guided swim workouts may be adequate.  

In terms of training structure, keep the following in mind: 

Pool vs. Open Water Swimming Workouts for Triathlon Training 

There’s no need to Google “shark migration patterns” yet. Yes, you will eventually want to swim in open water. But you’ll also spend plenty of time in the pool. 

Triathlon swim courses are usually marked off in open water, where depth, marine life, temperature and chemical balance are left to the elements. Natural bodies of water also don’t have walls, reliable depth measurements or lane ropes at regular intervals. And although your progress will be monitored by a safety crew on race day, and courses will be marked by buoys, these won’t prevent cramping or overexertion.  

These are all great reasons to gain confidence, competence and comfort swimming in a pool before training in an open water venue. For pool sessions, make sure you know opening hours and lane swimming times, the pool size and any rules you'll need to follow.

Prior to any open water swim session, familiarise yourself with any venues you plan to use, both for training and on race day, and pay extra attention to any factors that could impact your physical safety.  

Make sure to consider tidal and rip currents, and read up on how to manage these if you're caught up in one. Research the local waters, including marine life and what to be aware of, expected water temperatures and any water quality warnings in the area. Also make sure you understand active swimming regulations and distance measurements.

Whether or not you’re new to open water swimming, remember that swimming in daylight hours with a partner or group is always a safer option.

Bike Training for Triathlon  

Whoever coined the expression, “...Like a fish needs a bicycle,” obviously wasn’t a triathlete. 

On race day, you’ll emerge from the water after the swim potion, put on your helmet, hop on your bike, and ride. The longest leg by distance in any triathlon, the cycling portion also involves the fastest top speeds and most reliance on equipment performance. 

As you bike train for an upcoming triathlon event or season, your chief aim is to build the endurance necessary to complete the cycling leg after swimming with enough energy left for the run. In the process, you should also develop a strong sense of familiarity with your bicycle, to the point where it feels like a natural extension of your body. 

To ensure you and your bike are a great match, always get a proper, professional-grade fitting well in advance. 

Bike Training for Triathlon: Equipment 

Cycling requires more technical (and potentially expensive) gear than any other portion of a triathlon event, but that doesn’t mean you need to splurge on experimental carbon fiber racing frames and wind-tunnel tests.  

Make sure to consult your specific race rules for details on allowable specs for bicycles, helmets, modifications and accessories. Often, race rules governing cycling gear will be based on those set out under British Triathlon Competition Rules.

Bike Training for Triathlon: Technique

Over long distances, and especially when sandwiched between a swim and a run in a large race event, the specifics of triathlon cycling technique require more attention than, “It’s like riding a bike.” 

Even veteran cyclists will benefit from a riding or training group led by experienced triathletes.  

Race rules are very specific on allowable cycling techniques and etiquette, and you won’t be able to consult the rulebook (or this guide) while you’re riding. But you can ask a more experienced friend.  

In general, always train how you plan to race. 

Some basic techniques to keep in mind: 

Road Rules and Etiquette 

Whether training or racing, always wear a helmet, avoid headphones and obey road rules. Most sprint distance race courses will be at least partially closed off to traffic, but exceptions over certain course stretches are always possible. Familiarise yourself with course routes and restrictions. 

Read through race rules thoroughly, as they tend to be exacting on allowable cyclist conduct. The reason: safety.  

Racing rules generally prohibit drafting, and promote equal wind resistance for every racer. You’ll also find guidance on race course situations such as overtaking another rider, being overtaken, allowable forms of propulsion on the cycle course and more. Read and remember these, and lean on the expertise of a cycling group. 

Often, race rules governing cycling conduct will be based on those set out under the British Triathlon Competition Rules.

Bike Training for Triathlon: Guidance and Structure

“Train the way you’ll race” is great general guidance for beginner triathletes, and involving other riders is a great way to do it. Look on the internet, social media or through local businesses to find a structured lesson or practice group.  

You won’t be the only person training for any given local event.  

You’ll also want to train for potential race day conditions, including expected elevation changes, as well as a variety of weather. This will require training outdoors on the road or a designated bike lane more often than on a stationary bike.  

In any self-guided cycling you do as a part of your training regime, remember the following: 

Stationary vs. Road Bike Workouts for Triathlon Training 

The indoor vs. outdoor workout debate in cycling does have an interesting quirk you can take advantage of for training purposes: in ideal conditions, piling on the miles is easier outdoors on an actual bike than on a stationary cycle. 

Since the issue of balance is eliminated from stationary bike workouts, their impact is more localised to the quads, hamstrings, calves and gluteal muscles. Additionally, the resistance dials and tracking mechanisms on stationary bikes allow for a more regulated and, potentially, intense workout than all but the steepest outdoor climbs. 

Incorporating stationary bike workouts early in your training routine can be a good way to build strength and stamina in key muscle groups. But in general, since you’re training for an outdoor race, you should ride outdoors as often as possible.  

Road biking will prepare your body and mind to thrive in race day conditions. Not only that, but outdoor bike workouts also work your arms and core muscles harder than a stationary bike will. 

Training through outdoor cycling will also help you build up cycling abilities before race day, such as understanding of how to adapt to adverse weather conditions, how to traverse varied terrain and deal with elevation changes, as well as road etiquette and best safety practices. You'll also understand how to troubleshoot minor equipment failures such as flat tyres, so if they happen on race day you won't be thrown off-course.

Treat safety as your highest priority when riding outdoors. Always wear a helmet, avoid using distracting audio playback devices (they’re not allowed in races anyway), consider visibility-enhancing clothing options and outfit your bike with headlight, tail light, pedal and wheel reflectors.  

Training in a group, on designated bike paths and during daylight off-peak traffic hours are all safe options.

Run Training for Triathlon  

By now, you’ve unclipped from your bike pedals, pushed your cycle into the change station, changed into your running shoes, quickly swigged some water and taken a deep breath. Here comes the home stretch.  

Do you have enough left? If you’ve trained well, you will. 

Run Training for Triathlon: Gear 

While the run portion of a triathlon doesn’t require much in the way of equipment, as the last stage of an already tiring race, everything you rely on will take on an increased significance.  

Take extra care when selecting running shoes, socks and apparel, and imagine you’re shopping for a version of yourself who’s already completed an open water swim and bike ride.  

For all running apparel, find a retailer near you with experience outfitting triathletes, and don’t be afraid to ask them questions.

Run Training for Triathlon: Form and Technique 

Proper running form and technique is more important for triathletes than for those just getting into running, for two major reasons:  

• Efficiency matters more for endurance sports such as triathlon than when running simply to maintain or improve your fitness level.

• Improper form caused by muscle fatigue and exhaustion are of greater concern in the run portion of the triathlon, the final leg of an already challenging course.

As you train, keep a close eye on your form and technique, especially at first. Remind yourself to adjust as often as possible. That way, it’ll be like second nature on race day as you fight against fatigue. 

Running Form and Technique Guidelines:

Run Training for Triathlon: Guidance and Structure 

As with training for the other triathlon portions, seek out guidance from a coach or group, and move your run workouts more exclusively outdoors as your training progresses.  

Treadmill vs. Outdoor Run Workouts for Triathlon Training 

The practical differences between indoor and outdoor running workouts, while considerable, are much less than the difference between pool versus open water swimming, or stationary versus road biking. Treadmill workouts, in moderation, are a vital tool for any triathlete in training. 

Keep the following considerations in mind:  

In any given run workout throughout your training, staying on the treadmill for the planned distance and speed won’t impact your training too much. Try to venture outdoors more often than not.

Beginner Triathlon Training Plan 

Before you start any training plan, ask your regular physician for a consultation on your overall health, ability and fitness for triathlon, as well as any recommended modifications.  

Logistically, you’ll want to establish access to a gym environment with pool, stationary bike and treadmill options. You’ll also want to find local venues for open water swimming, as well as outdoor route circuits for bike and run workouts. Your options should mirror the conditions and elevation changes you’ll encounter on your race course, and you may also look for resistance and endurance training loops with even more challenging climbs than any you’ll find on race day. 

Plan to train five to six times per week, with one day each week reserved for an extra long session (known as a “brick” workout) that incorporates two or three of the triathlon portions, and at least one day of rest. In the final week of taper before each event, you’ll want to switch the roles of rest and training, with only one or two longer workouts and much more rest. 

Triathlon Training Workouts 

Your triathlon training plan will consist of two major workout types:  

Triathlon Training Plan - Sample Schedule 

Your workout pacing can vary according to fitness level, and individual workouts may be modified for indoor or outdoor based on weather conditions and safety.  

You may also wish to seek out training groups or coaching, and incorporate techniques and recommendations into your self-guided workouts. 

The most important modification you can make to personalise a triathlon training plan is to build up your endurance more slowly, and with greater focus, when approaching any triathlon leg with which you have relatively less confidence or experience. Adjust endurance distance percentages downward and frequency upward for any triathlon portion where you’d benefit from extra work. 

Triathlon training is the responsibility of each participant alone. The following sample schedule starts 12 weeks away from race day.
