2025 Skills & Safety Clinics
Our Skills & Safety Clinics are designed to help swimmers of all ability levels become more confident and efficient swimming in open water. The Clinics consist of two parts: (1) a 60-minute live (or on-demand) webinar offered and (2) 90-minutes of in-water instruction by our coaching staff offered on-site at Marsh Creek State Park The webinar and in-water instruction are offered on multiple dates throughout the season and you may attend whichever sessions are most convenient for you. You do NOT need to select which dates you will be attending when registering for the Clinic. While it would be beneficial to attend the webinar prior to the in-water instruction, it is not required. During the webinar session, we will review the unique aspects of open water swimming, talk about the most common factors causing anxiety for athletes, and provide strategies for eliminating or minimizing these factors. In addition, we will discuss key equipment selections which can help to improve your comfort and performance in an open water environment. We will also address any specific questions or concerns you may have about swimming in open water. During the in-water session, our coaches will demonstrate and teach key open water skills (including sighting, drafting, buoy turns, and triathlon swim starts) and provide you with an opportunity to practice them in a small group setting. During the second half of this session, you will have the chance to hone your new skills on the practice course that we have set up for our training swim participants.
