The difference in our average speed vs average power makes me think I should lose some weight/work on my aero's. Only 4kg difference but an average ride is at least the same weighted, but for a lot less speed.
I think for me I think I should have stretched (to lessen the chance of cramps) and do more training on endurance at a higher FTP (whatever that will be) to get comfortable to be riding at a painful zone.
In all seriousness, I do weigh 71kg (give or take a few pork buns) but the timing chip shows clearly whew it all went wrong for me...
