Welcome to the Cohasset Kids Triathlon! Join us on Saturday, July 13, 2019!!! Note: we will open registration for this event on March 1, 2019.

We are thrilled to stage a fun and safe triathlon event for kids ages 6 - 14 years of age. With the coordination of the Cohasset Swim Center, the South Shore Music Circus, the Cohasset Public Schools, and the Cohasset Board of Selectman this will be a sensational opportunity for your kids to get involved in a healthy and active sport. All of the participants in this event will be a winner!


We believe we have designed a perfect course to introduce our young athletes into the sport of triathlon. Nothing is more important than the safety of every participant. We will work very hard to ensure all of our young participants are safe and having a great time. Unless there is an emergency, there will be no cars on the course while the athletes are racing. Race volunteers and safety personnel will be positioned throughout the course. Athletes understand to take special precaution on the bike course and run course in particular when cross the railroad track on Sohier Street.

Triathlon Distances:

8 & Unders - 50 yards swim (2 lengths), 1 mile bike, .75 mile run

9 - 11 Age category – 75 yards swim (3 lengths), 1 mile bike, .75 mile run

12 – 14 Age category– 150 yards swim (6 lengths), 1 mile bike, .75 mile run

Note: we also offer a “Splash and Dash” option - that is, just to swim and run if that is a better option for your child.


Age Requirement: you must be at least 6 years old to compete.

USA Triathlon member: All athletes must be members of USAT to compete in any of the races. If you do not have an annual membership, you must purchase a one-day membership for $15 (which will be charged when you register).

Important Race Information: Packet pickup will require photo proof of identity (driver's license, passport, etc). All USAT members are required to show their USAT membership card when picking up their packets. If you do not have your membership card, you will be charged an additional $15 for a one-day license, which can be credited toward your future renewal USAT membership fee. Athletes that paid for a 1-day license do not need to bring anything to show for their USAT info, but will still need to show a photo ID.
