If it's any consolation, that really hurt - more than any other ride for ages.
As for the start, I was happily pedaling away at 33mph thinking how it was feeling quite easy when it gradually dawned on me that the speed was remarkably static - even when I stopped pedaling completely! My trainer had become unplugged - had to sort it all out, find the ride again and start from the beginning. At least it happened early on!
Bill - you seemed to suffer a dead-stop when we were together which was annoying (especially for you!). I felt bad and started to slow down to wait for you, then remembered about AAAC breathing down my neck in the league so carried on - sorry!
