Can’t stress enough how different the water is when you transition from pool to open water.

Even for the experienced swimmer, getting used to the change can really disrupt your calm, jack up your heart rate and make the swim way harder than you want or expect.

Terrible way to start a bike in a triathlon! (Or any open water swim, for that matter)!

Let’s get in together and be ready to go. Practice old skills, implement new techniques, try fresh strategies, all in the actual race setting.

Last chance to join our clinic on Sunday May 3! Wetsuit optional, water temps expected 71-73 degF and air temps around 50 degF.

Pre registration required. Link in bio.
