Welcome to the 10th Annual Nantucket Triathlon!
Many thanks to all of our returning athletes for bringing such a healthy and inspiring energy to Nantucket in the middle of the summer and for showing Nantucket - its officials, its residents and its visitors - that the triathlons that we put on and that that you make happen - are a positive influence on the island on every level.
Please join us for a very special 2018 event. Registration is open! Register soon as we expect a large turnout this year.
