I ran the Mt. Sneffel’s Half Marathon this year, and I need to preface this by saying that thanks to a landslide, the course had to be changed. So I can’t speak for the usual rout rom Ouray to Ridgway, instead we started in Ridgway and turned around at 6.5 miles. This meant it was mostly uphill on the way out and downhill on the way back.
The easiest miles were definitely 1-2 and 6.5-9 when you got that nice downhill stretch. But man, miles 4 to 6.5 were a grind – it was all uphill and really tested me.
There weren’t a lot of aid stations or crowds along the way, but on the plus side, there were no lines for the porta potties! And the views were absolutely stunning the whole time, which made the tough parts more bearable.
Overall, even with the course change, it was a beautiful race and I’m glad to have been able to check Colorado off my list this year!
