I don't want to, and my training has really helped but I just can't keep up with the guys on my group rides.
Our ride last night was 45km and the first half ranged from 33-46kph. I could only keep up to the halfway point and I was lost. And the first half was into the wind which of course always dies at 7pm so there is no reward on the way back.
On the way back I rode alone (again) at a steady 33-35kph. I've only been doing the group ride thing for a month but I am putting a lot of training miles in.
Short of strapping on a rocket I don't see how I can ever keep up.
