Founded in 1988, the Rock Run is both a team relay and ultra running event that

stretches about 50 miles around the perimeter of Nantucket Island, Massachusetts.

The race is held over the summer each year and all proceeds are donated to the

Nantucket Autism Speaks Resource Center.  There is a mandatory meeting at Children's

Beach on the Friday night before the race to discuss the Course and post race party.

We understand that many competitors require lodging and/or transportation to

Nantucket Island, so we do not collect race fees prior to the Pre-Race Meeting.

To learn how to register and for more information about the race please see

our Application page. Also, visit our Links page for information on transportation,

lodging, and more.
