ABTA BONDED · FULL FINANCIAL PROTECTIONABTA BONDED · FULL FINANCIAL PROTECTIONTraining for a triathlon is a genuine balancing act across three disciplines, and it’s easy to get the balance wrong. These are the ten mistakes we see most often — and what to do instead.
Rest days aren’t time off from progress — they’re when the progress actually happens. Overtraining without adequate recovery leads to fatigue, burnout and, eventually, injury. Schedule rest days as deliberately as you schedule hard sessions.
Triathlon lives or dies on smooth transitions between disciplines. Neglecting brick sessions — training two disciplines back-to-back, most commonly bike-to-run — leaves your legs unprepared for how strange that transition feels on race day. Work one into your week from early in your build phase.
If your only swimming has happened in a pool, open water on race day can be genuinely disorientating — waves, currents, no lane lines, other swimmers everywhere. Get open water practice in well before race week, ideally more than once.
Under-fuelling training leads to poor sessions and slower recovery. There’s a lot of noise in the sports nutrition market — read labels, use your judgement, and treat your pre-race and in-race fueling as something to test in training, not something to figure out on the day.

Chasing speed while ignoring form is a fast route to inefficiency and injury. Technique work in all three disciplines pays for itself many times over — it’s the single biggest thing a coached session at a training camp can give you that solo training can’t; see our full coaching team‘s credentials for the kind of eyes you want on your form.
Untested gear on race day is a gamble — discomfort, blisters, or an outright equipment failure at the worst possible moment. Test everything, from wetsuit and goggles to tri-suit and running shoes, well before the race.
T1 and T2 are often an afterthought, but they can cost you real time. Practise transitions specifically — set up a mock transition area during training and run through it until it’s automatic.
Assuming race-day weather will match your training conditions is optimistic at best. Train in heat, wind and rain occasionally so nothing on race day is a genuine surprise.
Starting a training block — or the race itself — at too high an intensity is one of the most common ways triathletes derail their own progress. Build intensity gradually and practise pacing deliberately, not just on race day. If you’re working to a tight timeline, our guide to training for a triathlon in three months covers pacing a compressed plan specifically.
Avoiding these ten mistakes is largely a question of structure and honest feedback on your technique — both of which a coached week does better than training alone. Take a look at our triathlon training camps and start training smarter, not just harder.
