Trail runners can now register for the 12th Annual Blue Hills Trail Races on Sunday, April 30 in the Blue Hills Reservation in Milton, Massachusetts.

There will be two events: the challenging 10-mile “Fox Trot” and the easier 3-mile “Bunny Hop.”

Early registration is important, as this popular event is limited to a total of just 250 entrants.

Organizers request a minimum $12 donation as a registration fee, and additional donations are appreciated. All race profits are donated to the Blue Hills Trailside Museum to support its nature-education programs for children.

The races are low cost, low frills. Racers don’t receive T-shirts or trophies, but the race has a scenic, hilly well-marked course staffed by many volunteers, with several water stops, computerized timing, and post-race refreshments.
