I was wondering if anyone knows and of the grades of the road up behind CSU stadium and along horsetooth res. The section I'm interested in is N Co Road 23, according to Google Maps, that is on the east side of the res and runs parallel. Several up-down sections there. I road that for the first time today and it kicked my butt. Google MyTracks said the max grade was 4.9% and I sure hope that is wrong. Thanks.
