For regular attendees at U.S. trail ultramarathons such as the High Lonesome 100 Mile, Leadville 100 Mile, and Western States 100, you might be familiar with a particular green singlet branded RMR — and the rapturous cheering which will erupt when one of these singlets passes through a checkpoint or crosses the finish line of a race.
