Predict Your Finish TimeBefore You Race
An AI coach asks about your fitness, your race, and your gear—then predicts your swim, bike, and run splits using sport science models. Free. No account needed. Takes 3 minutes.
Sprint, Olympic, 70.3, or Ironman — any distance
Built by triathletes. Powered by the same sport science engine behind Guava Tri coaching.
Right now, you're probably guessing
You've Googled “how long does a triathlon take” and gotten generic averages that tell you nothing about your race. You've tried online pace calculators that just divide your 5K time by distance—as if running off the bike is the same as a fresh 5K.
Or you've posted on a forum and gotten 15 answers from 15 people who don't know your bike fitness, your swim background, or whether you own a wetsuit.
None of these account for open water vs. pool speed, the impact of your equipment, how transitions actually work, or the fact that your run pace drops after 40km on the bike.
Three minutes to your prediction
No forms. No spreadsheets. Just a conversation with an AI coach that knows what to ask.
Answer a few questions
The AI asks about your race distance, swim pace, bike fitness, run time, experience level, and equipment. It adapts follow-ups based on your answers—like asking whether your swim pace is pool or open water.
Real models do the math
Your data runs through proven sport science: pace scaling that accounts for longer distances (Riegel extrapolation), bike power converted to race-day speed, open water adjustments for sighting and conditions, and transition estimates matched to your experience level.
Get your race-day plan
Not just a number. You get predicted splits for every leg, a confidence range so you know the margin, equipment upgrade analysis with specific time savings, and a pacing strategy tailored to your fitness.
Here's what a prediction looks like
Splits, strategy, equipment analysis, and honest confidence bands—not a single number pretending to be precise.
Your Prediction
Olympic Triathlon — June 15
Confidence
±6%
Estimated Finish Time
2:52 – 3:12
Equipment Opportunity
Aero helmet could save you 2–4 minutes on the bike leg based on your speed and race distance.
Race Strategy
Start the swim easy—find your rhythm by 200m. Bike at a “comfortably hard” effort (180–190W if you have a power meter) to save your legs. Run the first km at 5:30/km, then settle into 5:15 pace.
Prediction based on a recreational triathlete with a 2:00/100m pool swim, 200W bike power (FTP), and 24:00 5K. Your prediction will reflect your actual data.
This isn't a pace converter
Open water correction
Pool pace doesn’t transfer 1:1 to a lake or ocean. The model accounts for sighting, drafting opportunity, and conditions.
Power-to-speed modeling
Your bike power or average speed gets converted to a race-day bike split factoring in your weight, riding position, and distance.
Run fatigue factor
A fresh 10K and a 10K after 90km on the bike are different races. Riegel extrapolation with fatigue adjustments reflects that.
Transition estimates
T1 and T2 times vary wildly by experience. First-timers average 4+ minutes. Experienced racers are under 2. The model matches your level.
Equipment impact
Aero helmet, deep section wheels, wetsuit, race belt—each gets a specific time-saving estimate calculated from your fitness and distance, not generic marketing claims.
What we don't model (yet)
Race day has variables no model fully captures: heat, wind, elevation profiles, nutrition execution, and mechanicals. Our confidence ranges account for some of this uncertainty, but they can't account for all of it. Treat your prediction as informed guidance for building a race plan—not a guarantee.
