At our farthest point, we descended McNeely Rd, which was a very new experience to me. I've never done a descent with such steep and tight switchbacks, so needless to say it was a bit hairy. Then, we climbed back up. 3 of us did, anyway. The climb is 1.6km, avg grade of 7.1% with sections at 17.1%. Needless to say, tougher than any other climb in Southern Ontario. It didn't help that my winter bike has a single 42t, so I was climbing in 42x28 (approximately equivalent to the second last cog on my road bike, 39x23). That was fun. Down Fifty road, and into Tim Hortons we went as we were now quite hungry and ready for a break at this point.
Following the refueling stop, most of the group went back up Fifty Road (no easy climb but gentler than the others in the area) while the same 3 of us decided to climb Wolverton Rd. instead. Wolverton is 1.3 km, avg grade of 8% with sections at 17.2% - similar to McNeely but 300m shorter and thus a little steeper on average. Also, the steepest part is a long stretch at 16-17% about 3/4 of the way to the top that just about breaks your legs.
