Marc Anderson of Mattapoisett is topping the leader board for the Massachusetts Summer Bike Challenge.

The riders and teams are tracked by the month. For the first week, Anderson and others like him have propelled Mattapoisett to first place.

Mattapoisett has now slid to third place with Fairhaven in first and Westfield in second place ranking. More riders and miles are needed to get Mattapoisett to no. 1.
