DS Boosters Race Postponed to September 13, 2026
New Date: September 13, 2026
It is with great sadness that we share this news: due to unforeseen issues with the high school facilities, we are unable to hold the 2025 Dover Sherborn Boosters Triathlon. We know how much this event means to our athletes, volunteers, and community, and we are deeply disappointed not to gather with you at the starting line this year.
We are already planning for our return on September 13, 2026, and look forward to making it our best race yet.
Registered participants may choose to roll their 2025 entry into the 2026 race or donate their fee to the Dover-Sherborn Boosters, a nonprofit that supports our student-athletes through funding for equipment, facilities, and athletic programs.
Thank you for your understanding, and for standing with us and our mission even in this difficult year.
