The Mountain Swim Series presents its unique Cliff Backyard Ultra Swim, one of the world’s premier high-altitude swims with a highly unusual format.

At 2,425 meters (7,957 feet) in altitude in the Rocky Mountains of Colorado, race director Geoff Hawksworth challenges swimmers to complete as many 1.5 km loops until they fail in Wellington Lake.
