The map shows the course, starting just underneath Harvard Bridge on the Boston side. The halfway point is around the tree in the car park just before the State Police Station and back the same route. Registration is important. Each runner will have two numbers, to be worn on the front and back of their shirt. You will be able to get pins there too.
Rules are minimal.
A team must have at least five people to avoid a forfeit, which puts the entire team out of the race.
