Boston Volvo's Turkey Trot - Boston/BrightonThis 21st annual 5k race in Brighton benefits the National Multiple Sclerosis Society in New England.

All runners get a free long sleeve tech shirt, and are entered into a post-race raffle, which includes over fifty 6-packs of beer and bottles of wine.

Proceeds from race benefit the Dedham Food Pantry and local Ripples of Hope community based service initiatives.

This annual 5k is mighty popular and usually sells out by the end of October and it's hosted by the Wellesley Turkey Trot Foundation, which is still in the process of selecting this year's race beneficiaries, according to the website.
