What you get

Five specific,
data-anchored findings.

Not summaries. Not generic advice. Findings anchored to your power, HR, and pace numbers, willing to contradict your memory of the race.

01 · Bike
Bike pacing
Normalized power, variability, Pw:HR drift. Where you burned matches and when the decline began.
02 · Run
Run execution
Opener, settle-in, back-half fade, final kick. Where you broke, and when. Not where you remember.
03 · Balance
Bike-run balance
Did the bike leave capacity for the run, or cost it? The answer matters for your next race.
Sample finding · Warsaw 70.3 · Run Analysis
“The run broke at km 5, not km 15. Out of T2 at 3:47/km, you settled to 4:08/km by km 5. Most athletes remember the second half as the collapse. Your file shows the pace ceiling was set at km 5.”
