Makes me think but I seem to push too hard through the W's any way so I don't mind the pace. This is probably the only race that it would help on but there would be a lot of passing to get ahead of the line before tree line. I don't think I would try it.

So. What if I start about ten minutes late ... so as to get a clear shot up the switchbacks ????
