Triathlon Calculators
Free triathlon calculators: total race time estimator, swim/bike/run pace targets, training zones, transition time, and brick tools.
Race time, split targets, transitions, nutrition and brick training. 8 calculators for triathletes. Single-sport pacing sits under Running and Cycling.
Transition time is the cheapest minute in the sport and the one almost nobody trains. A sloppy T1 and T2 give away three or four minutes across a race, which is more than most athletes gain from an entire training block. It also costs nothing in fitness, just a rehearsed sequence and elastic laces.
Wetsuit time savings puts a number on buoyancy, and the result runs against intuition. The gain is largest for weaker swimmers, not strong ones. A strong swimmer already holds a good body position in the water, so there is less for the neoprene to correct.
Race nutrition works in carbohydrate per hour, and the ceiling is a gut limit rather than a preference. Practise it in training. Race day is a poor time to discover what your stomach will tolerate at effort.
The race time and split target pages work from your own recent times rather than from an age-group table. That matters most on the run, where a split predicted from a standalone 10k is optimistic by several minutes. You arrive at it having already swum and ridden, and no fresh-legs time accounts for that.
Open Water Swim Sighting Distance Calculator
Calculate sighting frequency and drift distance for open-water swims. Plan how often to lift your head to stay on course in lake, ocean, or river triathlons.
Triathlon Wetsuit Time Savings Calculator
Estimate seconds saved per swim leg by wearing a triathlon wetsuit. Compare buoyancy gain by suit type and water temperature across all race distances.
Triathlon Brick Training Calculator
Plan your bike-to-run brick training sessions. Calculate target bike and run paces based on your race goals and current fitness.
Triathlon Race Nutrition Calculator
Calculate calorie and fluid needs for your triathlon by distance and intensity. Get hourly carbohydrate intake targets and hydration amounts for each segment.
Triathlon Race Time Calculator
Calculate your total triathlon finish time from swim, bike, and run paces plus transition times. Works for sprint, Olympic, 70.3, and Ironman distances.
Triathlon Run Pace Calculator
Calculate your triathlon run pace. Convert run time to pace per km or mile and predict finish time for Sprint, Olympic, or Ironman run legs.
Triathlon Split Time Target Calculator
Calculate target swim, bike, and run split times for Sprint, Olympic, Half-Ironman, and Ironman triathlons from your goal finish time and transitions.
Triathlon Transition Time Calculator
Estimate and optimise your T1 and T2 transition times. Know exactly how much time transitions add to your triathlon finish time.
