Nice course, small-town feel

This is a small race, without a lot of flash or spectators. But It's very well run, with great course support. The course was enjoyable, with amazing views of the front range and open skies. We look forward to running it again next year!

Age brackets

I love this race & what it is there to support. I am really unhappy that they decided this year to do away with age brackets. that was one of the reasons that I first did this race. I am 65 & without age brackets, I really don't have a chance. I hope they bring them back for next year!!!

Top-notch in all regards

This is an incredibly well run Colorado Event. Also, a course which offers great mountain views and quality mixed surfaces for its Athletes. Highly recommended as one of the best.

My husband and I have still not received our medals. Would love to know if we will get them. Loved the race and the people. Just disappointed we did not get out medals.

Great Race - Great Course - Great Energy

I have been either a participant or have "coached" runners for this run for years now. Every year it's a hit! The course is well-marked. The pre and post food is great. And the beer garden - so awesome!!!

Best local half marathon!

I enjoy this race, because one, it’s for a good cause. It’s close to home and convenient. The views of the front range are lovely! The race directors put on a great race and a lot of energy. Lots of goodies at the bib pickup. I will be doing again!

Carbon Valley - Wonderful

I am their loyal Ambassador. I ran it before serving as such. It has always been a favorite. Vintage Firestone, Colorado. Which includes great views of Longs Pk.
