I knew that the long downhill was coming, my strategy for group rides is to attack on the descents so that people don't have to wait so long for me at the top of the next climbHe was going for a Strava segment, Col and I were cruising uphill unaware of that, then when I got round the corner and saw that lovely long downhill, I had to see what speed I could get it up to about 40mph as it turned out.
