The Island Ripple Run returns to Diamond Cove, Great Diamond Island, and Little Diamond Island! This is a 4-mile race around two islands in beautiful Casco Bay, just off the coast of downtown Portland. Participants will enjoy ocean views as this run follows picturesque island roads and wooded paths around Great Diamond Island, over the sandbar that attaches Great Diamond and Little Diamond Islands at low tide, around Little Diamond Island, and ends on the north side of Great Diamond Island near the tent site.
All proceeds from this race go to the Dennis Farrell Memorial Scholarship Fund at Rippleffect, located on neighboring Cow Island.
The Kids Diamond Dash kicks off the morning followed by the Island Ripple Run. Light refreshments will follow the races.
