High altitude training is scientifically proven to increase ATHLETIC performance. 


We work with running programs in various ways. Some groups lead their own camps on our grounds with minimal guidance from us. Others work closely with us to plan a custom training camp based on their team's specific altitude training goals. We also cater to individuals' training goals.

We provide access to 250+ continuous miles of single track trail, 150+ miles of wide trail, quiet country road loops, lake loops, high desert dirt roads and 14,000ft peaks all within close proximity. Our founder and affiliate coaches know the area well and can guide you and your team along these trails. CRR caters to distance running disciplines but can handle all paces/levels of runners from beginners to professionals to national teams.

CRR also hosts high altitude training camps for other sports. The Adidas-sponsored youth basketball program, Young Vets, hosts 20 athletes and coaches at the ranch each summer.
