About the Race

Portland’s first multisport race for children, The Portland Kids Duathlon, is presented by Benchmark Real Estate. The race gives young people ages 3-12 an opportunity to participate in the fast-growing world of multi-sport racing. The run, bike, run format of a duathlon is fun and approachable, a great race for non-swimmers and triathletes alike. A bike only event for our youngest athletes as well as those with special needs makes the event even more accessible. All young athletes will finish the race with a smile on their face, a medal around their neck, and a boost of self-confidence and pride. All profits from this race will be donated to the Foundation for Portland Public Schools. Both in-person and virtual race options available.

Course

Transition will be at the triangle in front of Payson Park with separate transition areas for each race. We are on Baxter Boulevard with out-and-back bike courses on the road and out-and-back runs on the trail. Courses will parallel each other to make for easy viewing for spectators. All roads will be traffic free.

NOTE: All participants will need to purchase an annual membership with the USA Triathlon (USAT) for an additional $10. This is because our race is sanctioned and supported by USAT. See details below. USAT has now made this a one time fee.
