The annual Santa Speedo Run, 2006

The event also has people that continue to come back every year.

Lanna Cohen, 31, of Somerville; Kyle Grady, 26, of Somerville; and Erica Lafreniere, 30, of Medford have all participated once before.

Grady is a teacher at Manchester Essex Regional High School, and his students raised the $200 for him to run this year.
