Perfect for running naked

Weather.com pegged the temperature near Copley Plaza at 47 degrees when John Perham crossed the finish line of the Boston Marathon a little after 3:30 p.m. Monday. The website noted that, with 17 mph winds, it felt like 39 degrees, and fans along the course would argue that it felt even cooler on this late April date.

Not Perham. No, it felt more like a day at the beach for him. A resident of Newton's Upper Falls, Perham crossed the finish line sans shirt, but wearing a large smile that indicated he was in no rush to dig a T-shirt out of the pouch strapped to his waist.

No shirt, no problem.

"The first run I did, I did two miles in 15 degrees," explained Perham. "Sweat was pouring off me. I thought, 'Hey! It's cold outside, I should be letting the cool keep me cool.'"

Unless temperatures dip below the teens, Perham skips a shirt (and even then he only prefers one that's open in the front). You can convince him to run in some light pants, but only because of the perspiration that can build up there.

In his mind, the conditions for the 113th running of the Boston Marathon were ideal.

"This temperature, this is perfect," said Perham. "Perfect for running naked."

Running shirtless earned Perham plenty of comments, particularly from the ladies near Wellesley College. He said he kept his hands warm by throwing high-5s to anyone that would reciprocate along the route.

Of course, not wearing a shirt leaves a dilemma about wear to pin your bib number. Once again, not a concern for Perham.

"I haven't qualified in years," he said with a laugh.
