The Mountain Swim Series is excited to be coming into its tenth year in 2024! This series provides experienced and organized Open Water Swimming to the Rocky Mountain Region. 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. This series offers the opportunity to swim and race in the open water at over a mile high in elevation.  

The 2024-series will consist of THREE events.

The first event will be 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.  Also, this swim will have an 18 and under 500 YD out and back race.

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 2024. We plan for 2024 to be a crossing for the year, but may be required to do an "out and back" (similar to 2020 and 2021) should COVID requirements become more stringent again.

The third event is the Castle 2.5K/5K/10K.  This event was started by Cliff Crozier and Karen Reeder, and is 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 and the overall series winners will be named at this event.

We are working with several venues to try and bring several new swims into the series this year, however, we have lost our long-term partners, Chatfield Reservoir, due to new special event rules at the venue. We regret to inform you that the long running Chatfield Classic and last year's Chilly Chatfield will not be held in 2024.

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 in good health and be able to consistently hold a 2:30 per 100 yard pace or faster.

See you in the water!!!
