Course details
The Nantucket Triathlon is a sprint triathlon with three consecutive legs on Nantucket Island: a swim, a bike, and a run. The course uses local roads and waterfront areas and finishes at the Jetties transition area.
The event legs and distances are:
- 450 yards swim
- 13.5 miles bike
- 3.4 miles run
Swim: athletes are grouped by age and enter a chute that forms two lines. The swim uses a time trial start with two athletes entering the water side by side every five seconds; a start clock counts down from five for each pair. Race time begins when an athlete crosses the timing mat at the water’s edge. The start is self seeded. Water temperatures are expected in the low 70s degrees and wetsuits are optional. After the swim athletes run up the beach to the upper parking lot near the tennis courts and enter transition.
Bike: athletes mount in a designated mount zone near the upper parking lot. The bike route is an out and back to Madaket and back to Jetties, and riders must keep single file with quick passes and an immediate return to the right side of the road.
Run: after racking bikes in the upper parking lot at Jetties, athletes run a 3.4 mile course that follows streets and waterfront areas including Madaket Road, Cliff Road, and North Beach Street. Three locations where runners and bikers may overlap are Nantucket Ave with Cliff Rd and North Liberty, Easton St with North Beach St, and the end of Hulbert Ave. These areas are staffed with police, volunteers, and signage.
