Event Details
Experience the thrill of our annual 4x4x48 Challenge – a 48‑hour endurance run where participants complete 4 miles every 4 hours. This year, the event kicks off at 6 PM on April 4th and concludes with the final leg at 2 PM on Sunday, April 6th.
All legs start and finish in front of Mackal Gym, following a scenic bike path. Whether you're an avid runner or simply looking to support a worthy cause, there's a place for you in this event!
We're excited to announce that URI President Marc Parlange will be joining us for some legs of the run, leading by example and inspiring us all to give our best for this important cause.
Our runs will start and end at Barlow Circle and participants will be able to recover from runs in Hillside Hall.
Participants should email us for more information regarding access to the recovery area.
