Run, jog, or walk in our wicked fast downhill mile race then join the Rainbow Day Party with a Purpose in the Town Park.

Inspired by the legacy of Sidney Mae Olson, the Rainbow Fund is on a mission to make every Massachusetts community a place where kids are free to move. Your support will help our nonprofit to build a bike park for kids and continue our work.

The course starts at the top of Summer Street in Andover and runners will fly down Summer and make one turn left onto Whittier Street to finish in the Park.  Celebrate that new PR with our Rainbow Day party in the Park.
