Core training principles

02:52 -

• In triathlon, as in any endurance sport, long-term progress is built on consistency rather than short, intensive bursts of training followed by extended rest.
• Training regularly, even in smaller amounts, is far more effective and sustainable—both physically and mentally—than alternating between overload and inactivity. This approach lowers the risk of injury, illness, and burnout, while maintaining motivation.
• Another key principle is that most training should be easy, with only a small proportion being hard. The widely referenced 80/20 guideline—approximately 80% easy and 20% hard sessions—is a good framework to follow. Hard sessions are essential for improvement, but they should not dominate the program.
• Developing the ability to gauge effort accurately, through metrics such as Rate of Perceived Exertion (RPE), is an important skill alongside the use of objective data like heart rate or pace. Easy and hard efforts should feel distinctly different, and understanding this difference is fundamental to effective training.
• Progress also relies on the relationship between training stimulus and recovery. Training itself is the stimulus, but adaptation occurs only with adequate recovery, which is primarily supported by sleep, rest, proper nutrition, and hydration.
• Especially for beginners, training sessions should be manageable to ensure the body has the capacity to recover and benefit from them. Recovery tools like ice baths or supplements are secondary to these fundamental habits.
• Specificity is another important factor—performance improves most in the activities and conditions in which one trains. For triathletes, this means regularly practicing swimming, cycling, and running, with extra focus on the weakest discipline.
• Training should also replicate race conditions whenever possible. While swimming training is best done primarily in a pool for technical reasons, open-water practice before race day remains valuable for environmental familiarity.
• Early in a triathlon journey, focusing on technique yields significant long-term benefits. Good form in swimming, cycling, and running improves efficiency, increases speed, and reduces injury risk.
• This includes technical skills such as bike handling, which can make a considerable difference in race performance. Neglecting technique in favor of purely fitness-based training may deliver short-term gains but will eventually limit performance potential.
• While beginners do not require highly customized training plans, some degree of individualization is important. Factors such as athletic background, work schedule, and injury history should influence how training is structured. Adjustments should be made based on personal response to the program, without overcomplicating the process.
• Progressive overload—gradually increasing training volume or intensity over time—is necessary for continued improvement. However, increases should be modest, avoiding the common mistake of progressing too quickly.
• The body can adapt to a given training load for weeks before needing an increase, and long-term progress often takes years. Patience ensures steady improvement without compromising health or motivation.
• Finally, it is essential to understand that different body systems adapt at different rates. Cardiovascular fitness can improve within days or weeks, but structural adaptations in tendons, ligaments, and bones occur much more slowly.
• This imbalance can lead athletes to believe they are ready for greater training loads when their supporting structures are not yet prepared, increasing the risk of injury. Progression in both volume and intensity must therefore consider the slower adaptation of these systems.

Micro cycles

13:56 -

• A microcycle in triathlon generally corresponds to a weekly training structure. For a beginner, this might consist of two swims, two bikes, and two runs each week.
• Another effective option is three swims, one bike, one run, and one brick session (a bike ride immediately followed by a run). For example, Monday could be a rest day, Tuesday a swim, Wednesday a brick workout, Thursday a swim, Friday a run, Saturday a swim, and Sunday a bike session. This arrangement distributes the disciplines evenly throughout the week.
• Athletes with a strong background in one discipline or endurance sports may be able to train three times per week in each sport. However, this would typically require incorporating double-session days, such as swimming in the morning and cycling or running in the evening.
• As highlighted in the training principles, most sessions should be easy, with only some containing higher-intensity work. It is common, particularly in triathlon, to have mixed sessions where the overall effort is low, but short bursts of intensity are included.
• For example, a predominantly low-intensity ride may still feature a few short sprints, or a technique-focused swim might include some fast 25-metre intervals. Intensity should be judged on the overall feel of the session: easy sessions typically fall within a 3–4 effort level on a 1–10 scale, while hard sessions are generally in the 6–8 range. Rarely should sessions reach a 9 or 10, as this increases the risk of overtraining and reduces long-term consistency.
• For someone training six times per week, one to three of those sessions might be harder efforts, depending on prior experience. A beginner might limit themselves to one or two hard sessions, while those with an endurance background may manage three—one each for swimming, cycling, and running. These harder workouts are usually best performed as intervals, although continuous tempo work can also be effective.
• An important consideration when planning a microcycle is to avoid stacking hard sessions on consecutive days. Spacing them out helps maintain quality and allows for better recovery.
• For example, an easy swim on Tuesday could be followed by a harder brick workout on Wednesday, another easy swim on Thursday, a longer easy run on Friday, a harder swim on Saturday, and a longer easy bike on Sunday.
• Regarding double-session days, they can be effective and often become necessary as an athlete progresses. However, beginners—particularly those new to endurance sports—should first establish a consistent routine with one session per day.
• Once this routine is sustained comfortably, a gradual introduction of one or two double-session days per week can be made, increasing only when the body is ready to adapt.

Mesocycle

20:20 -

• While a mesocycle can be defined in different ways, a common and effective approach is to structure it as a sequence of load weeks followed by a recovery or “deload” week. A simple and widely used format is three weeks of regular training load followed by one easier week.
• A deload week does not mean complete rest. Instead, it involves a reduction in training stress, which can be achieved by slightly lowering overall volume and, more importantly, reducing intensity. For athletes already training at relatively low volumes, it may be sufficient to maintain the same volume while removing or significantly reducing high-intensity work.
• The extent of the adjustment depends on the demands of the preceding load weeks. For beginners, a practical approach is to keep most sessions easy during the deload week, allowing the body to absorb the accumulated training, recover fully, and prepare for the next block.
• This cycle of progressive loading followed by relative recovery helps promote sustainable improvement while reducing the risk of fatigue, injury, and loss of motivation.

Macrocycle

21:30 -

• At the macrocycle level, we consider the big picture—the full training year. Long-term improvement depends on maintaining consistency for most of the year, but that does not mean training for all 52 weeks without a break. Planned downtime is essential for both physical recovery and mental rejuvenation.
• I recommend taking two full weeks each year completely off from structured swimming, cycling, and running. During this period, you can remain active through other activities such as walking, hiking, or playing recreational sports, but without following any structured training plan.
• Following these full rest weeks, it can be beneficial to have an additional one to two weeks of unstructured swim, bike, and run sessions, done purely based on enjoyment and without specific objectives.
• This annual reset supports the adaptation process, which follows the principle that stimulus plus recovery equals adaptation. Just as recovery is necessary on a daily, weekly, and monthly basis, it is equally important on a yearly scale.
• Incorporating deliberate rest into your macrocycle ensures you are physically and mentally prepared to resume structured training and continue progressing.

How to distribute training

23:18 -

• For beginners, swimming should be given particular attention—not necessarily in terms of total training time, but in training frequency. Because swimming is a highly technical discipline, frequent practice is more beneficial for skill development than simply increasing session length.
• For example, three 30-minute swims in a week are more effective for improving technique than two 45-minute swims, even though the total volume is the same. If you live or work close to a pool, it may be worth increasing frequency to four shorter swims per week, especially if you already have a reasonable cycling and running background.
• Cycling is an excellent discipline for building general fitness, with strong crossover benefits for running and a very low risk of overuse injury. It allows for longer, higher-volume sessions without excessive physical strain, making it ideal for accumulating substantial training volume.
• Running offers equally high, if not greater, fitness benefits than cycling, but it comes with a significantly higher risk of injury, particularly for beginners or those with limited running background.
• Progression in running should be gradual and carefully managed, with particular caution for those prone to injury. In some cases, personalised guidance may be needed to develop a safe progression plan.
• As a starting point for overall volume distribution, a typical beginner might allocate approximately 25–30% of weekly training volume to swimming, 45–50% to cycling, and 25–30% to running. For example, in a five-hour training week, this could translate to around 2 hours 15 minutes of cycling, 1 hour 30 minutes of swimming, and 1 hour 15 minutes of running.

Training volume

26:32 -

• In terms of training frequency and total weekly volume, a practical starting point for most beginners is to aim for two sessions per discipline each week.
• This is the minimum effective frequency to meaningfully develop both skill and discipline-specific fitness, particularly in swimming, cycling, and running. Training only once per week in a given discipline can maintain some fitness but will limit technical improvement and specific conditioning.
• These sessions do not need to be long to be valuable. Short workouts of 15 to 30 minutes still contribute to the overall training load and, over time, play a meaningful role in driving adaptation. Avoid the mindset that only long sessions are worthwhile; even brief workouts are productive if performed consistently.
• In my eight-week beginner plan leading to a first sprint triathlon, the opening week totals approximately 3 hours and 15 minutes of training, while the highest volume week reaches about 5 hours and 15 minutes. Across all eight weeks, training is scheduled on six days per week, with one rest day.
• I am confident that if two groups of equally matched beginners were compared—one training 4 to 4.5 hours per week over six days for eight weeks, and another training 8 to 9 hours per week but only for four weeks—the consistent, lower-volume group would achieve greater overall improvement. The key driver is regular, repeated stimulus over time.
• While progressive overload will eventually be necessary, beginners can make substantial gains with relatively low total weekly volume, provided it is applied consistently week after week.
• Training six days per week may seem unrealistic at first, especially for those with busy schedules, but it is achievable with careful planning and shorter, more frequent sessions.

Tips for training consistency

28:55 -

• To maintain consistent training frequency, several practical strategies can make a significant difference.
• First, establish and stick to a consistent sleep schedule. By going to bed and waking up at regular times, you create the opportunity to incorporate early morning workouts into your routine.
• This can free up time that might otherwise be lost to rushing through morning obligations such as commuting or taking children to school. The discipline required for a consistent sleep pattern often pays off in added training opportunities.
• Second, consider incorporating training into your commute. If your location and logistics allow, cycling or running to and from work can be an efficient way to integrate endurance training into your day without requiring additional dedicated time.
• Third, make use of lunch breaks for short sessions. Even 20 minutes of focused training contributes meaningfully to your weekly load and can help maintain consistency. Short sessions are particularly valuable when time is limited.
• Finally, stack shorter workouts when necessary. If a day’s schedule makes training impossible, compensating the following day with two short sessions—such as a 30-minute swim followed by a 20-minute run—can help maintain overall frequency. This “brick” approach is an efficient method to train multiple disciplines in one time block, even if each session is brief.

Strength training

30:25 -

• While we will explore this in greater detail separately, it is important to note that even a simple strength training routine can be beneficial for beginners. Whether it involves bodyweight exercises or gym-based weightlifting depends largely on your prior experience and comfort with strength work.
• If triathlon performance is your primary goal rather than building maximum strength, there is no need to dedicate extensive time to the gym.
• One or two focused 20-minute sessions per week can provide significant benefits. If you have more time available, adding additional sessions poses no problem, but for most athletes with limited time, the aim should be efficiency—achieving the greatest benefit in the least amount of time.
• Strength training in this context should be purposeful, supporting your swimming, cycling, and running without detracting from them. Rather than accumulating hours simply to “tick the box,” the focus should be on high-quality, targeted work that aligns with the specificity principle discussed earlier. This approach ensures that strength training complements, rather than competes with, your triathlon training.

How to measure improvements

31:45 -

• Knowing whether you are improving is a key part of structured training. The purpose of applying the principles and building a consistent program is ultimately to enhance fitness, race readiness, and overall performance. While races themselves can serve as clear indicators, there are several other effective ways to track progress.
• For beginners, improvements are often obvious. Moving from being unable to swim 50 metres to swimming 200 or 300 metres continuously, for example, is clear evidence of advancement without the need for detailed measurement.
• Beyond these noticeable leaps, subjective self-assessment is a valuable tool. Signs such as reduced perceived effort during workouts, less breathlessness, quicker recovery, and feeling more energetic all indicate positive adaptation to training.
• A more structured method is to log your training sessions, including a rating of perceived exertion (RPE) for each one. This can be done without purchasing specialised equipment.
• For example, if you regularly run a set five-kilometre loop, record both the time taken and the RPE in a simple spreadsheet. Over time, you may observe that you are running faster at the same RPE, or maintaining the same pace with less effort.
• The same principle applies to cycling and swimming. Adding short subjective notes after each workout will further help you reflect on and recognise progress.
• Periodic benchmark tests can also be used, provided the conditions are consistent. For example, completing the same parkrun each month at maximum effort can offer clear, objective data. You can also design your own time trials in swimming, cycling, or running.
• However, these tests are optional. While they can be motivating for some, they should not become a source of stress or pressure to perform. Over-testing can be counterproductive if it undermines enjoyment or leads to anxiety.

Common training mistakes

34:59 -

• When it comes to applying training principles and building a structured program, there are several common mistakes that can undermine progress.
• The most significant is inconsistency, which is often caused by doing too much too soon and leading to injury or burnout. It can also stem from underestimating the importance of regular training or from failing to establish daily habits and routines that make consistency possible. Maintaining steady, manageable training loads over time is far more effective than sporadic peaks followed by long breaks.
• Another frequent mistake is performing every session at a medium-hard or hard effort. As discussed earlier, effective training requires a balance—primarily easy sessions complemented by a smaller proportion of hard ones. This balance promotes improvement while minimising setbacks.
• Many beginners also fail to apply the adaptation equation correctly. While overloading the body with excessive hard training is one side of the problem, the other is neglecting recovery. Insufficient sleep, lack of rest days, absence of easier weeks, or inadequate nutrition all limit the body’s ability to adapt. Recovery must be planned and prioritised alongside training.
• Neglecting technique work is another issue, particularly in swimming, but also in bike handling and, to a lesser extent, running form. Technical skills are harder to correct once poor habits are ingrained, so the early stages of training are the best time to focus on them.
• Closely linked to consistency is the mistake of ignoring early signs of injury or fatigue. Addressing minor issues promptly—such as taking a couple of days off running for a developing niggle—can prevent far longer lay-offs later.
• Finally, many athletes overcomplicate their training plans. While structure is important, there is no need to obsess over every detail. If you find yourself overthinking instead of acting, it is often better to simply get out for a bike ride or a run. Training should be deliberate, but it does not have to be overly complex to be effective.
