The Rock Run is a professional-grade, ultra-endurance, off-road race with a grassroots feel.

In 1988, a local Nantucket Lifeguard trained to be the first to run around the entire island of Nantucket in a single day. Jim Storey completed this feat in memory of his father while fundraising over $2,000 for charity that year. Many years later, the race has had only a few minor modifications, mostly to the course (due to nesting shorebirds), but the core principles and the incredible effort required to complete the race have not changed. Still held every summer, the Rock Run welcomes regulars and newcomers, soloists and relay teams, to battle it out for the coveted “Cobblestone Cup” on one of the most beautiful islands in the world.


Through Fingerprints, Inc., a 501(c)(3) tax exempt organization, 100% of the race fees go to charity. Our goal is to keep growing the race every year so that The Rock Run can donate more and more to worthy causes.


Although the race benefits charity, the Rock Run is not a "fun run" by any stretch of the imagination. It makes a Tough Mudder or even an Ironman event look like a summer camp sack race. The Rock Run is a full day, grueling competition in which the course requires runners to swim, run on all manner of beach surfaces, choose between running ankle deep in sand or waist high in crashing waves (or swimming around beach obstacles, etc.), all while trying to span all or a portion of the almost 50 mile run-able perimeter of Nantucket as quickly as possible. The competition is absolutely fierce. In 2013, there was less than a one (1) minute difference between the first two (2) finishing teams. After 50 miles. Our top solo athlete (a 7 time Rock Run solo champion) finished the race in just shy of nine (9) hours. And although victory is sweet, many teams compete for the challenge of the race. In the end, the Rock Run is more than an athletic competition, it's an undeniable accomplishment. The bragging rights that come along with completing the Rock Run are undeniable.


Warning: this race is contagious. Fast friendships are required as teams often have to work together to get out to some of the more remote check points around the island. After completing a leg you become an alumni within the Rock Run community and will find even years later you can come back to the same race and be surrounded by familiar faces.


The easiest way to forget about tight, aching calves, bloodied and blistered feet and mosquito bites is to join us at the Post Race Party held the night of the race. Here you'll have a chance to compare times and exchange war stories with your fellow Rock Runners. The Cobblestone Cup is awarded, emails addresses are exchanged, and teams begin forming for the next year. The friendships last forever.

We look forward to seeing you on Nantucket - the Rock - this year and for years to come.
