The climb starts relatively flat near the bottom, slowly gets steeper, flattens out in the middle, then kicks up for the last mile. In the P/1/2 we did ~16 minutes for our fastest lap. It's similar in grade to the Round Mountain climb in the District Road Race. After the summit there is a short descent with a turnaround at the bottom. It's very difficult if you're not positioned near the front of the field because you go from 40mph to 5 mph then back up the climb.
