The 11th Annual 2019 Nantucket Triathlon Registration Page

Welcome to the Nantucket Triathlon. Registration for the 2019 event opens on Tuesday, January 15th at 8:00 am EST

Please choose from one of the race categories below to start the registration process. Please consider a donation (of any amount) to help fund a four year scholarship for a hardworking, entrepreneurial Nantucket High School senior or graduate of NHS who strives to be active member of the workforce or play an important role in small businesses on the island.

Note: unlike most races, the registration fee below INCLUDES all registration services fees. The only additional fee to the registration fee is the USAT One Day License fee if you are not a USA Triathlon member.
