🦌 About the Refuge

Centuries ago, these lands were hunted and fished by Nipmuc Tribes. Later, they were farmed by colonists, intersected by a railroad, and used for military training. You will run past military bunkers that were in use when the area was known as the Sudbury Training Annex, which was part of Fort Devens. The US Army transferred the land to the US Fish and Wildlife Service in 2000, establishing the Refuge.

Since then, the Refuge has become home to freshwater wetlands, oak and pine forest, and shrubland that support many types of wildlife, including wading birds, songbirds, raptors, beaver, bobcat, white-tailed deer, and various reptiles and amphibians.

Proceeds from this race will help fund improvements to three refuge sites in MA and a volunteer coordinator who will assist visitors to the refuge with nature education and programming.

🎉 Post-Race Festivities
