The Sharon Triathlon - Sharon, MA

The Sharon Triathlon takes place on August 9, 2026, in Sharon, Massachusetts. The event offers three entry types: Individual, Relay, and Individual AquaBike, and is open to participants aged 11 and older. The venue is centered on Lake Massapoag near 181 Pond Street.

The swim occurs in Lake Massapoag and starts and finishes on the beach. The swim distance is 1/2 mile. Water temperatures in summer are typically warm and wetsuits are listed as optional.

The bike leg follows a single loop around the lake and into nearby communities. The course distance is 12.3 miles on generally good road surfaces; local participants regard it as a time trial style course. The run is a lakeside loop of 4.4 miles that passes tree-lined homes and offers substantial shade for August conditions. The run finishes back at the park beneath a finish arch where an announcer identifies arriving participants.

On-site parking and additional lots at the nearby high school are used for race-day parking. Course maps and additional race information are provided by the organizer. A post-race barbecue is mentioned in organizer materials. Visit the organization's website for the most recent information.
