This was my first Half Marathon. As it’s in December, the unpredictability of Colorado weather means it could be 10 degrees or 60 degrees. It was in the low 30’s for my race.
The course is 95% paved bike trail with only a few dirt spots. The scenery is nice as the course runs along the creek. Race support is good with ample aid stations. There is some elevation change, but it’s minor. Race organization was good.
