I had trepidation about drafting, and agree with the advice to know or at least be able to gauge the person in front. I pedal with much less effort, because you need less effort when drafting, of course that's the point, and it gets appreciably easier the farther back you are in the paceline. You could just be stronger, or it was the effect of the pull. I also had a tendency to speed up when I took the lead, which is a no-no, the idea is to conserve energy as a group. We do 30 second pulls. I sure did appreciate it with a friend at the century this weekend, especially the last 20 miles in headwinds.
