Shawn McEntee, of Brooklyn, N.Y., was all decked out for the run. This is McEntee's second year running. He was participating with Chris Jones of Roslindale, who was running for his fifth year, Sandy Tichnor of Brighton, Sean Hennigan of Watertown, and R.J. and Rebecca Schmitt of Watertown.
This group got to Lir early for the pre-run festivities. Many had not stripped down to their Speedos yet.
