The Mountain Swim Series is excited to be coming into its seventh year in 2021! This series is designed to bring a new level of Open Water Swimming to the Rocky Mountain Region. With prizes for the top three males and females in both wetsuit and non-wetsuit divisions, this series offers the opportunity to swim and race in the open water at over a mile high in elevation.  

The 2021-series will consist of four events.

The first event will be the Solstice Swim in Longmont, CO. In this event, participants have the option of swimming either a 1.2 or a 2.4 mile course.  This event is a great warm up for the Castle 10K at Lake Wellington or for other swims later in the year.  New this year - Shorter 18 and under race - 500 YD swim.

The second event is the hugely popular Carter Lake Crossing in Berthoud, CO. This event is located at one of the most picturesque reservoirs on the front range. Carter Lake is excited to bring this event back in 2021.  Due to COVID-19 precautions, this will be an out and back swim, similar to 2020.

The third event will be the Chatfield Classic. This event will be held at the Chatfield Gravel Pond and participants will have the option of swimming either the 1-mile course, or the 2-mile course. 

The fourth event is the Castle 5K/10K.  This event which was started by Cliff Crozier and Karen Reeder, will be held at Wellington Lake.  It offers swimmers the highest timed 10K swim in the United States at approximately 8,000 feet.  Swimmers will have the option of swimming a 2.5K, 5K or a 10K swim in this beautiful reservoir.  There is also the option for pre-event camping the night before. This is the final event of the year. 

All Mountain Swim Series events will be insured and supported by safety watercraft, lifeguards, and paramedics/EMTs, however, any person signing up for these events should be a competent swimmer and be able to consistently hold a 2:30 per 100 yard pace or faster.

See you in the water!!!
