Open Water Swim Racing Options

We are only ONE MONTH away from our first open water race of the season, slots are filling up FAST, and registration is OPEN! Every participant gets a race shirt with their entry, so check out this year’s shirts below.

We have an exciting line-up of swims for this year and are including one additional race, a 500 YD swim at the Solstice Sunset Swim event. This distance will be a great opportunity for new open water swimmers, new triathletes, and KIDS! Any kid who participates in this race will be receiving a finisher prize!

The dates for the swim series are as follows:

Solstice Sunset Swim – June 26th, 2021Starting earlier, at 3pm this year! This event includes a 1.2 mi, 2.4 mi, and the NEW 500 YD swims!
Registration closes on Sunday June 20th, and if you sign up after June 10th, we cannot guarantee that we will have the correct shirt size for you.

Carter Lake – July 17th, 2021No day of registration. This is a 3mi out-and-back swim!
Registration closes on Sunday July 11th, and if you sign up after July 1st, we cannot guarantee that we will have the correct shirt size for you.

Chatfield Classic – August 15th, 2021Limited to 200 participants, so please sign up in advance! This event includes a 1 mi and 2 mi swim.

The Castle 2.5K/5K/10K – August 28th, 2021This is the highest altitude organized marathon swim event in the country! We will have the camping option again on Friday night – which you’ll find through the swim registration site. Camping is $40 for a 4 person site and will decrease your morning day of drive! 

Registration information for the year can be found at

We always need volunteers! If a significant other, friend, child (16 and over) is coming with you, we would love them to volunteer with us! If you are trying to decide to do one of the swims or new to open water swimming, volunteering is also a great opportunity! We couldn’t do this without our volunteers! In 2021, we will be continuing the tradition of giving our volunteers a free race entry after a volunteer shift!
