I enter an event "3R Park Perimeter Loop Flat Race - 3 Laps (29.1km/18mi 378m) (D)" today.
Set off, chase a bunch of folk and leg it up the hills to exhaustion, best placing 167th position.
finish event upload etc...
When I get here on zwiftpower my performance appears to have been ignored because I tried too hard and produced too much w/kg.

So apologies to anyone with whom I was competing today, I won't be pushing you or me.
Drafting, half-wheeling my new friends.
