Reuter Hess Reservoir Castle Rock CO 80108 US
Start Date: 2019-07-27

This open water swimming oasis has been the hottest venue in Colorado since our first open water swim back in 2016.  Who's ready for round 3?  Don't delay, last year we sold out in just a few months!

‚ÄčThe course will be set up as a 1.2 mile out and back, with the option to swim two laps for a 2.4 mile swim.  We'll also have a 1/2 mile swim option for beginners!  We'll have refreshments and raffles post event as we post your times.


Please note that if you miss your chance to dive into the Rueter-Hess waters this July 27th you'll need to wait a full year before getting another chance!  This event is limited to just 200 athletes so don't delay on registration, last year's race sold out by March 1st!
