A pack of runners accomplished a major feat Sunday by running nearly 150 miles just this weekend alone.

The runners were led by two-time World Marathon Challenge champion and Bostonian Becca Pizzi.

They started in Great Barrington on Saturday and completed 31 legs of relays through the day and night ending at the Boston Marathon finish line Sunday morning.

They ran to raise money for the Dave McGillivray Finish Strong Foundation. Founded by the Boston Marathon race director McGillivray, the non-profit's mission is to build kids' self-esteem through running, reading and acts of kindness.

McGillivray ran in this weekend’s event.
