Ginger Holton retired from a desk job in banking — and now the main thing she counts is how many Citi Bike miles she logs in a day.

Holton, 63, is the top female pedal pusher with the bike-share program, logging more than 5,900 miles since she signed up in 2014, a few months after she retired from the Depository Trust & Clearing Corp.

“I like to ride,” Holton said Sunday at Citi Bike’s fifth-anniversary party in Prospect Park, where she was a guest of honor.

“There’s just something about being out in the air and riding.”

Holton says she bikes between her apartment on the Upper East Side to volunteer gigs in Central Park and with the ASPCA.

“I say ‘yes’ to everything now, now that it’s so easy to get around. I do things I never would have done if I had to ride the subway.

“It’s everything I do. If I go to the grocery store, I take it. If I go to meet a friend for lunch, if I want some exercise — everything I do, I do with Citi Bike,” she said.

Joe Miller cuts an even wider swath through the city.

The 33-year-old East Village dog walker has pedaled an estimated 14,378 miles since he joined Citi Bike four years ago.

Citi Bike said that’s the most miles of any rider in the system.

“I’m honored, but not surprised,” a sweaty Miller said as he held his helmet with one hand and scarfed down a piece of anniversary-party cake with the other.

Miller said he started using the bike service because it was a quick way to get between dog-walking assignments. But accumulating miles via the Citi Bike app turned into an obsession last year, he said, when he joined the company’s system-wide bike-relocation program, Bike Angels.

Miller said he began working every free moment to help unlock bikes and move them between docks to help balance the system, for which he receives reward points and a small stipend.

“I threw myself at it completely,” he said.

Julie Wood, a rep for Motivate, Citi Bike’s operator, said when the program began five years ago, there were many doomsday predictions about accidental deaths.

But despite averaging more than 70,000 rides a day, there has been only one fatality.

A 36-year-old investment banker from Manhattan died after colliding with a bus last June.

Holton and Miller said they feel very safe on the sturdy blue bikes.

“I’ve been doored by cabs twice,” said Miller. “ But, thankfully, the baskets in front of these things are nice shock absorbers.”
