Celebrating Endurance - The 100 Mile Club

rue to the tradition of ultrarunning, Anchor Down Ultra is meant to serve as an immense challenge for the most hardened runner. It’s a grinding course under the challenging summer conditions, and competing in any of the three events is an accomplishment. However, there are some that toe the starting line with the dream of conquering the legendary 100 mile distance in under 24 hours. To those, this page is dedicated.

Cheers to the following 100 Mile Finishers, who have met the ultimate achievement on the shores of Narragansett Bay. The following have covered 100 miles or more is less than 24 hours at the Anchor Down Ultramarathon. We congratulate those who have gone the distance.
