About the Dewey Beach Sprint Triathlon

The first Dewey Beach Sprint Triathlon was held on September 14, 1996. It was held in the back of what was then called Gary’s Surf Spray Café on New Orleans Street in Dewey Beach, Delaware. The after party was held on the roof of the building. The following year it was also held on the same street but quickly outgrew the venue and has been held in the Delaware Seashore State Park ever since. It’s a no frills, grass roots community event and a Dewey Beach tradition that brings athletes and their families from near and far to the resort area.

We have simply strived for a safe, enjoyable and fun triathlon with a fast and scenic course while keeping the money within our community.
