The Human Potential Running Series has always focused on community first. Our series was born out of our incredibly popular “Fat Ass Series” that was once a staple in Colorado’s Front Range (2011-2016). Today we welcome members of our community to lead us in our mission to build a better and more unified trail and ultra community by hosting numerous group runs each month under the leadership of a select group of volunteer run leads.

The calendar below lists all of our races, trail work days, and other HPRS events; but its primary function is to list our Group Runs in the hopes that many more of you will join us by engaging as a member of our community (new or veteran) along the way. We’d love to see you on more than just race or trail work days.
