Gorgeous trail with great mountain views. Awesome volunteers and yummy food. Loved the ice bath afterwards awwww. Highly recommended especially if you want to PR or BQ.....fast downhill coarse.
I beat my last marathon by 20 MIN! This truly is a great course for a PR and a BQ attempt.
Amazing race. Beautiful course with awesome volunteers. I got a pr and a BQ.
Beautiful run and wonderful experience even running in the rain! would definitely do again!
Just ran my first Tunnel Marathon and had a fabulous experience (plus a 20 min PR and a BQ!). Well organized, great route. Loved the finish line! Loved the cold water tank and the massages!
