Ultramarathons in Leadville

Sunday, July 19 · Leadville, Colorado

The TransRockies Run Half Pint unfolds over three days in July around Leadville, Colorado, covering 35 miles total with nearly 7,000 feet of climbing across multiple stages. This multi-stage format lets runners experience different terrain each day while returning to basecamp each evening, creating a unique blend of adventure and community that sets it apart from typical point-to-point races. Running at Leadville's 10,000+ foot elevation means thin air will be a factor from the first step, and afternoon thunderstorms are common in Colorado's high country during summer. The course details vary by stage, but expect the terrain to showcase the rugged landscape around this historic mining town—from alpine meadows and rocky ridgelines to old mining roads that wind through the surrounding peaks. The fully-stocked aid stations and drop bag system help manage the logistical challenges of a multi-day event. Runners who thrive on variety and don't mind the effects of altitude will find this format appealing, especially those looking for something beyond the typical single-day race experience. The shorter Half Pint option makes the multi-stage concept more accessible than the full distance, though the elevation and mountain conditions still demand respect and proper preparation.
