Half Marathon, 10K, 5K
Most races are designed for one person: You. Your PR. Your medal. Your ego. Running is, by its very nature, a deeply selfish endeavor.
In November, we flip the script.
Welcome to The Unselfish Ultra: an HPRS event built entirely around thinking of someone other than yourself.
This is not about chasing an award or feeding your Strava profile. It’s a multi-hour reckoning across the Denver Metro, designed to remind us that we share this space and that our legs can lift others up.
