Good Way to Get CO Done

This course has less elevation changes in it than many in CO. However, it's still at altitude so, unless you live at altitude, expect it to feel tougher and be slower than your usual time. Organization was good, but there are a lot of races going on consecutively, which I'm not a big fan of (in addition to full & half, there was a relay, a 10 miler, and a 10k all on the same morning/venue). At least they didn't start at the same time haha. There's a 5k the day before- maybe they could shift the 10k & 10 miler to Saturday?? The course is okay; the highlight is running through Mile High Stadium twice. Also runs through a fire station (interesting). Otherwise standard stuff on roadways mostly. Some music and some nice spectators, great volunteers of course. 48th race marathon or longer distance for me, I recommend this race to anyone doing states that doeesn't want to seriously beat themselves up. :)
