Swim (Olympic – 1.5k, Sprint – 750m) – CLICK HERE FOR COURSE MAP

The swim is a clockwise course, starting under a large inflatable arch in front of the DCR McCormack Bathhouse and finishing on the beach nearby. The course will be marked with bright buoys and you will need to keep the buoys on your right the entire timeThe finish will be marked with large inflatable columns.

Dorchester Bay has become one of the cleanest urban bodies of water in America. The water temperature is currently in the low 70s. However, because of their buoyancy, wetsuits are recommended for all athletes as a safety precaution.

Swim waves are assigned based on gender and age groups. The last waves will be novice men and women. The first wave of Olympic age group swimmers is scheduled to begin at 6:20 AM. Waves will go off every 8 minutes.  There will be safety boats and lifeguards in the water to monitor the swim.

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

 


 

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 must retrieve their gear once all of the bikes have returned from the course.


 

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

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

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. The entire bike course will be closed to vehicular traffic. Both sides of William Day Blvd will be caution-taped to prevent pedestrians from crossing the road at non-monitored spots, and it will be closed to crossing while there is two-way bike traffic. However, we cannot entirely control pedestrian crossing. Please be aware that people may try to run across the road without permission during the bike portion of the race, so keep your head up and pay attention to what’s ahead.

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 5.5K) – CLICK HERE FOR COURSE MAP

The run is a cross-country style course that begins by exiting the Transition Area and follows the coned route onto Day Blvd. Turn left onto Day Blvd, and cross over to Moakley Park. The entire course will be in, or around, Moakley Park, and will be on paved sidewalks / trails.. After completing one full lap, Sprint athletes will head back toward the Transition Area / Finish Line, while Olympic athletes will continue straight for a second lap.
