Forensic analytics for serious triathletes.
Pre-race start-list intel, lap-by-lap session forensics, race-day debriefs vs the field, race projections, fuel timelines, and a Coach you can actually ask questions to. Built on the data your watch already captures, no extra logging, no vibes.

What you get
Lap-by-lap forensics
Every interval, every drift, every dropped pace flagged against your prescribed plan. No more 'felt good': see the truth.
Per-workout AI analysis
Claude reviews each session and writes a forensic note across 5 sections: what worked, what didn't, what to adjust. Pick the voice that fits: balanced, conservative (Friel-leaning), aggressive (FasCat-leaning), or race-week taper.
Race Scout — who am I racing?
Paste the race's public start-list URL plus your distance + age group. Race Scout pulls the cohort, ranks each competitor against mytriranking, and tells you exactly who's ahead of you and who's behind on paper. Pre-race intel, not vibes.
Race-day forensics
After every race, drop the chip-time URL and Race Analyser builds a per-leg debrief: where you executed, where you bled time, where you sat in your age-group. Per-discipline lap charts, body battery + stamina drift, power curve on the bike, all benchmarked against YOUR training fitness, not generic age-group numbers.
Ask Coach
A conversational AI scoped to your training data alone. "Why has my run pace plateaued the last six weeks?" → grounded answer with actual numbers, not generic advice.
Form & fitness curve
CTL · ATL · TSB tracked daily so taper and peak hit when you need them, not when you feel them.
Brick-derived race pacing
Race-day projections that calibrate from YOUR brick workouts, not a generic +8s/km penalty.
Daily readiness
Body battery, sleep score, HRV, and the day's planned intensity feed a single GO / MODIFY / SKIP recommendation. No more 'I feel OK' guesswork: the data tells you when to back off.
Race-day fuel timeline
Pre-during-post carbs scaled to your weight, ride duration, and goal intensity. Minute-by-minute intake schedule for race morning, when to take the gel, when to drink, when to top up.
Race Analyser · Olympic-distance debrief
Finished the race. Now see what actually happened.
Upload the .fit + the chip-time URL. tri-ai stitches the watch data with the official splits, ranks you against your age group, and writes the per-leg debrief, grounded in YOUR training fitness, not generic age-group benchmarks.

Cross-cutting takeaway
The fade is on the bike, not the run, bike-leg durability is the limiter. Next block: 3× sub-threshold (88-93% FTP) rides per week for 4 weeks, no all-out efforts on the bike until race week.
Example output, your debrief uses your own thresholds, your own brick history, and your actual results page.
