Best vacation of my life.

My family's visit to Grand Teton has so far been the best vacation of my life. Glacier has been on my bucket list ever since. This race is 6 days after my 50th birthday so this will be an awesome birthday gift!

The courses are always incredible

Have done Rocky Mtn twice and Yosemite once and can second that you guys are great. So much easier to deal with than a certain Mouse controlled race series and the courses are always incredible. Looking forward to Teton in June!
