More than a start line

We grew up exploring the deserts, mountains, canyons and forests of Arizona. Getting outdoors is part of our heritage and is in our blood. We feel most alive on a trail, experiencing the solitude and the big views.
We are more than an event management company. We are committed to a vibrant community centred on being active outdoors. Our weekly group run started for this purpose and it really feels like family.
It's the little things that count. From course markings and pre-race emails to chip timing and convenient packet pickups, our events strive to impress. Did we miss something? We guarantee to make it right.
What is an event if it isn't fun? We aim for a laid-back vibe that just makes you have a good time: music, wood-fired pizza, beer gardens, new friends, and costumes whenever possible.
