Everyone will get an extra hour of sleep on Saturday night, thanks to daylight saving time. Dave Berni will need it more than anyone.

Berni, 34, is the New York Mets assistant clubhouse manager who is pulling a rare double this weekend. He is working the World Series and running the All About 75 Hard. “I knew I was running it all season,” Berni said. “When the Mets got to the postseason, it felt like [the World Series] was going to happen because of the two dates conflicting.”  

“I was thinking about deferring,” Berni said. “But I am running for a charity.”

Though Berni has done only three three-mile runs this week, he hasn’t really rested.  

The Mets are down two games to one against the Kansas City Royals. Berni will be at Citi Field tonight and tomorrow night to work games 4 and 5. Tonight, he expects to be up until 2 a.m. to finish the players’ laundry, and then he will catch a few hours of sleep on a couch in the clubhouse. He will wake at 4:30 a.m., grab a bagel and yogurt from the clubhouse kitchen, and take a car service into Manhattan. There he’ll transfer to a bus that is transporting everyone running for the Bulldogs Care Foundation to Staten Island.

The New York Road Runners has moved him into the first wave that takes off at 9:50 a.m. His original goal was to finish in four hours. “Now I just want to finish,” Berni said.

Then Berni will head straight back to Citi Field following the race. “I think I’m going to take the train to the stadium,” he said. “Someone told me if you have a medal from the marathon, you get a free subway ride.”  

Berni started running two years ago, nudged by a comment from a child. “My 6-year-old daughter said I was fat,” Berni said. “Maybe I did put on some weight.” Last year, he regularly ran with Mets bullpen catcher David Racaniello, who was training for the 2014 NYC Marathon. (Racaniello ran 3:41:48.)

Berni got inspired to do the full 26.2 miles himself. He applied via the lottery, but didn’t get in. So he decided to run for the Bulldogs Care Foundation, a nonprofit that uses sports to help New York City area youths overcome scholastic failure, obesity and high-risk behaviors like gang violence.

Berni, who has lost 30 pounds since he took up running, says he loosely followed Hal Higdon’s training plan. Berni’s workouts have gone well with the exception of his longest run, an 18-miler. “I had inflammation in my knees and I broke down,” he said. “But a great thing is that the Mets’ doctors were able to help me out.”

Everyone in the clubhouse has been supportive of Berni’s marathon pursuit, including Berni’s boss, who is a marathon finisher herself.  

Unlike most finishers who will kick back and relax on Sunday night, Berni will be anxious to get to his office.  “I want to work that night,” he said.
