Greenfield Triathlon : August 2, 2026, Greenfield, MA
The Greenfield Triathlon is a USAT-sanctioned event held in Greenfield, Massachusetts, with all race proceeds benefiting the Greenfield Recreation Department. The event offers both individual and two- or three-person team entries in two distances. Entry limits are 200 for the International race and 250 for the Sprint race. Competitors must be at least 10 years old on race day. USAT membership or a one-day license is required; one-day licenses are not available for youth 17 and under. Awards are given for overall finishers, relay teams, top age-group finishers, and additional special recognitions. In past years, a high bacteria count in the river has occasionally required replacing the swim with a short run.
Course and race specifics
- International: Swim 0.63 miles, Bike 30.28 miles (4 loops), Run 6.5 miles
- Sprint: Swim 0.31 miles, Bike 15.14 miles (2 loops), Run 3.08 miles
Swims take place in the Green River on buoy-marked courses with athletes entered in age-wave groups; wetsuits are highly recommended and the event requires the provided swim cap. Bike routes use local roads including Nash’s Mill Road, Leyden Road, Eunice Williams Drive, Green River Road, and Colrain Road, with mount/dismount zones and looped circuits. Runs follow local roads and return to the transition area for the finish. Swim waves are sent at set intervals and timing is chip-based. A one-day clinic and multi-week Sunday training programs have been offered in lead-up to the race. Visit the organization's website for the most recent information.
