Did I say it stopped? I meant my heart rate 'stabilized'

Check out ZP, I maxed a nice 107 HRM for the whole ride
I may have another go tonight but at a more relaxed pace. I'll have another 'proper' go over the weekend when the legs are a bit more recovered. It will all depend on the group I get into though. Yesterday the group I was in (that I got dropped from with the drop out) was a good minute or more behind any other rider, and the group behind that I joined up with was a minute behind us. It's often the group you get in with rides like this that dictate your final time

It's that first 5 mins that decide what the best time you'll achieve 40 minutes later
