First State Duathlon 2025

A duathlon is an athletic competition featuring running and cycling events, and consists of a running leg, a cycling leg, and another running leg. The First State Duathlon is a trail-race duathlon, with all three legs of the competition taking place on natural surface and gravel trails.

The First State Duathlon returns! Delaware Interscholastic Cycling League is excited to bring back this fun and family friendly competition to Bellevue State Park this summer with the help of Spur Impact! Join us on Sunday, July 20 for this year's race and the first one since 2019!

The First State Duathlon is a fun duathlon competition that will take place on the trails at Bellevue State Park in Wilmington, Delaware.

There are three legs to the race: a trail run, followed by a trail bike ride, followed by a shorter trail run. Athletes can race as an individual or with a 2 or 3 person relay team. Competitors will need to provide their own trail bike for the bike leg of the race. We recommend using a mountain bike, cycle cross, or hybrid bike (with durable tires). All ages and skill sets welcome.
