Patrick Rodio of Collingswood sets off on a “21 for 21” race — 21 miles for the Class of 2021 — to raise money to buy $75 yearbooks for Collingswood High School seniors unable to afford them. Joining him on May 2 were fellow joggers who ran 21 miles in repeated loops around Knight Park, across from the school. Rodio, 48, a seasoned marathon runner, organized a similar event last year, which helped raise enough money to buy yearbooks for every senior. To donate, go to www.collscares.org/2021-fund
