Join ATW Dorney Triathlon - August 2025
Take on a Sprint or Standard distance triathlon and experience the thrill of racing at this iconic Olympic venue! This is a draft-illegal event.
With clear waters and flat, scenic grounds, you'll enjoy a beautiful swim followed by fast bike and run courses. It's the perfect setting for a chip-timed personal best or for those who prefer not to race on open roads.
Our team of volunteers will be there to guide you and cheer you on all the way to the finish.
For those who prefer to skip the run, we offer an Aquabike option (swim and bike).
