A point-to-point course in Dorchester Bay that begins on the beach near the McCormack Bathhouse and follows a trapezoidal course the finish on the beach near the Bayside Expo Center. Wetsuits are recommended. Athletes should plan to walk approximately 1/4 mile along DCR Carson Beach to the Swim Start. The walk is mostly on trails and sand, so shoes are not needed.

In the event of poor swim conditions, Race Management and the Department of Conservation and Recreation reserve the right to shorten, alter or eliminate the swim course.

Final wave assignments and start times will be finalized and posted a few days before the race.


 

The Transition Area

The Transition Area will be located in the grassy field, referred to as DCR Mother’s Rest. It will be a flow-through design, where athletes enter at one end and exit at the other. Athletes will be assigned a rack space that allows plenty of room for gear. The Transition Area will be secure and monitored, and only athletes, volunteers, and staff will be allowed inside. Athletes can retrieve their gear once all of the bikes have returned from the course.


 

Bike (Olympic 35K, Sprint 17.5K) – CLICK HERE FOR BIKE MAP

The course is a looped course on a number of wide, car-free roads, including DCR Day Blvd.

The entire bike course will be closed to vehicular traffic and managed by State Troopers. There may be pedestrians that try to cross the road at unauthorized locations, so please be alert and aware of this potential situation, especially in the middle part of the course (near L Street).

Bike traffic will be two-way and will utilize all of DCR Day Blvd. All vehicles will be removed from the course prior to the start of the race.

Drafting is not allowed in this triathlon, and there will be officials on course monitoring cyclists. Any athlete caught drafting will be subject to time penalties. DCR Day Blvd is wide enough to allow for safe passing on the left. Athletes must stay as far to the right as possible while on the bike unless they are overtaking another competitor.


 

Run (Olympic 10K, Sprint 3.4 miles) – CLICK HERE FOR RUN MAP

The course is a point-to-point route that follows DCR Day Blvd to the Sugar Bowl, then goes part way around the Pleasure Bay before turning around and returning along DCR Day Blvd. The finish is back at DCR Mother’s Rest Field.

There will be water/aid stations approximately every 1.5 miles with water and electrolyte replacement drink.
