ah ha, it was a crit, but there were only 14 racers, and 5 in the group. The rest were shelled off the back. And I was definitely drafting most of it.

But I also didn't take into account the profile of the course (you can read about it/see it in the Greenbelt topic I posted)

But I am basically trying to get numbers in order to have a baseline for the future. This was my first race and I am interested in trying to track improvement.
