Regarded as the toughest, roughest and most beautiful 50 mile trail runs in the country. It runs point-to-point along the Highline trail from Pine to Christopher Creek, Arizona. Chris Epper and I had the opportunity to crew for Pat Colleran during this epic race. This is not a leisurely trail run. This terrain was mean and nasty. This is the type of race that will make you strong in ways that you won't fully understand.
