About this race
The 19th sprint triathlon features a swim in Farm Pond, a kettle pond, followed by a bike course through hills and backcountry. The run uses challenging backroads with a double transition course. Finish Olympic stadium style at Dover-Sherborn High School, then enjoy the post-race Breakfast Brunch Buffet. This community-organized, volunteer-driven event supports the Dover-Sherborn Boosters, providing athletic experiences for children.
