After another sell-out in 2026, MammothMarch returns to Northeast Florida where Dunns Creek State Park will once again kick-off our season of hiking events. Located south of a sharp bend in the St. Johns River, more than 6,200 acres of natural communities are represented in Dunns Creek State Park which makes it a beautiful home to our iconic 20-mile adventure. Tucked in between Jacksonville, Orlando and Gainesville, and just around 90 minutes away from either city, Dunns Creek makes for the picture-perfect winter hiking getaway in Florida. Master the challenge and spend a beautiful and challenging day hiking 20 miles at a stretch. Getting your finisher medal, you will be exhausted, but proud and happy...as well as part of our amazing community of nature lovers, hikers and MammothMarch addicts. 2027 — MammothMarch Northeast Florida — Race Roster — Registration, Marketing, Fundraising
