Here’s how Stevenson’s cross country team hopes the Baltimore Marathon plays out: As their coach, Dave Berdan, leads the race near the end, the Mustangs in the crowd egg him on. “We’ll shout, ‘You can hurt for five more minutes,’ which is what he yells during our meets,” said Patrick Watson, a sophomore from South River. “That should bring a smile to his face.” Could that happen? Berdan, 36, has won the marathon at the Baltimore Running Festival twice (2013 and 2015) and looms as a favorite Saturday. This year, for the first time, members of the Stevenson team plan to be there for support — and to turn the tables a bit. Dave Berdan, Stevenson cross-country coach and two-time Baltimore marathon winner, works with his team. “We’ll root for [Berdan] all during the race, then we’ll catch the finish,” said Ryan Siegel, a sophomore from Flemington, N.J. “Hopefully, he’ll be all alone out there, just him and the clock. And we’ll use his own lines against him. It should be fun.” For his part, Berdan — in his fourth season as Stevenson’s coach — enjoys having his charges on board. “It’s good motivation for me,” he said. “It’s a long race and it’s nice to see faces you know, to push you along. I’m sure they’ll mess with me too, saying the same stuff I tell them, like, ‘Don’t settle in [with a group], keep passing.’” Last year, Berdan, of Owings Mills, finished fifth, having pooped out late. It was his first marathon since hip surgery the winter before. That he completed the course at all, he said, was in deference to his team.
