About

The Mountain Swim Series provides experienced and organized Open Water Swimming to the Rocky Mountain Region. Swim and race in the open water at over a mile high in elevation! The Solstice Sunrise Swim is the first event in the series and a great warm up for other swims later in the year.

Participants have the opportunity to swim either a 500-YD race, 1.2 mile race or a 2.4 mile race. The race will start as a mass in-water "wet" start.  Divisions will be both non-wetsuit and wetsuit for both men and women for each race. Awards will be given out to the top three finishers in each division for each race.  Prizes are provided for the top three males and females in both wetsuit and non-wetsuit divisions for each race and for overall series winners at the end of the year.
