This year serves as the the second year of our Ambassador program, and just like everything else... we are always looking to improve our programs so this year we are excited to add the following training runs, that will be hosted by one of our Ambassadors.  Our dedicated Ambassadors are experienced trail runners that live in the Denver or Fort Collins Metro areas. Each Ambassador has selected a training run and area, that will help runners prepare for one of our upcoming races in April and May.

For more information on each of our Ambassadors, please feel free to visit the AMBASSADOR PAGE.   

Additional training runs are being planned to help prepare runners for our races throughout the summer. Until then we hope you are able to join us on the trails...  

The Endurance Race Series is proud and honored to work in, and support one of the best communities in the category of endurance sports. We are always looking for ways to build and educate the trail running community, get new or novice runners involved, and how to  help those experienced trail runners find ways to train for their upcoming events.

In 2017, we are proud to announce our own set of training runs through our Ambassador program, and our new training partnership with Life's 2 Short Fitness, a trail running training group designed for women. We hope that these programs are helpful in your training and you are able to join one of our ERS Ambassadors on a training run this year.
