🏃♂️🌲 Mastodon Rumbler Trail Race – Run for Fun, Run for a Cause! 🌲🏃♀️
Back for its second year, the Mastodon Rumbler Trail Race returns on June 20, 2026, inviting runners to experience one of New Brunswick’s most unique and storied landscapes. Set in the breathtaking Whiterocks Hills of Hillsborough, NB, this trail race blends rugged terrain, deep local history, and strong community spirit into one unforgettable event.
🦣 Why “Mastodon Rumbler”?
Whiterocks Hills is where history truly rumbles beneath your feet. Long before modern trails existed, mastodons once roamed this land. Centuries later, mining operations carved their mark into the hills, shaping the terrain you’ll tackle today. As you race through winding trails and challenging elevations, you’ll be moving through layers of prehistoric wonder and industrial heritage that make this course unlike any other.
