01
Bike pacing
Normalized power, variability, Pw:HR drift. Where you burned matches.
02
Run execution
Opener, settle-in, back-half fade, final kick. Where you broke, and when.
03
Bike-run balance
Did the bike leave capacity for the run, or cost it? The answer matters.

Sample finding · Warsaw 70.3

“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. The final 2km at 4:34/km was the last expression of a fade that started much earlier.”
