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. :)

Challenging course but few spectators

Very well organized, from the start (with each corral having 90 seconds difference, which allow you to run confortable the first miles) to the end (very well separated from the half marathon arrival). Nice to run through the fire department station (with entusiastic firefighters cheering), and also through the Mile High stadium and the Arts and Design Academia. I liked the course, despite the lack of spectators in some parts. A little bit difficult to run with relayers in the narrow parts, as they go with different pace. Also with the 10 milers, that made a small 'bottle neck' when they join marathoners for the last part of the course. Great job from the volunteers and police. Nice expo at Mile High, and very good technical shirt, which is very comfortable to run with. I think that they should have timing at the 13.1 mark. I agree that time splits could be better.

Extremely well organized and staffed!

The race-day coordination was extremely efficient. City Park is easy to access, the corrals and start sequence were the best I've encountered in 21 marathons and the water stops were well sequenced and staffed. For football fans, going to Mile High Stadium 3 times (once for registration and twice during the race) is awesome.
