If you live around the northwest Denver metro, and are looking for a place to grind on hill climbing, then William F Hayden Green Mountain Park is a pretty good place to hit. Not particularly scenic, but certainly some variable training terrain.
Hit the trails ~8:30am, with my partner, to low levels of people and returned to a similarly low-key parking lot for a Saturday morning ~10am. M/F pit toilets at parking lot.
