Ingrid Remak helped instill a devotion to tennis in her children and grandchildren. They coach, they play at the collegiate level and they win tourneys. She boasts about their accomplishments in the sport, as any good mom or grandma would.

But when it comes to the court, sometimes lines are drawn.

Remak tells of how it’s been “family against family in tournaments. It’s hard, it’s part of it,” she says. “I don’t want to beat my own children.”

This is what a family feud, fitness-style, looks like for the Remaks, where the tennis trait stretches across three generations.

The matriarch, of course, is Ingrid.

A petite woman with a short bob of pearly-white waves, she picks up the rack0et year-round.

She’ll walk to nearby Bryan Park for matches if she has enough time, and it’s indoors at Indiana University Tennis Center during the cooler months. She enjoys skiing and swimming at the IU pool when it opens up later this month. But tennis is her true passion—right down to the “I ❤ soccer” white ankle socks she sports.

“I just love doing it,” she says. “It’s good exercise.”

Remak calls herself a late bloomer to the game.

She started playing in her mid-20s, and that was, well, quite some time ago. She’s probably more likely to share the secret to her notorious drop-shot than her age. “Just say I’m an old lady,” she quips when asked just how old she is.

This “old lady” plays tennis several times a week; sometimes twice a day. Remak seems to be an in-demand partner so she’ll book a game in the morning and one later in the day.

“I’ve been lucky that people are still playing with me,” she says. She is twice the age of some of them. “It’s a social thing on top of getting together and playing.”

On this recent breezy Sunday afternoon, Ingrid is playing with friends at the far-court at Bryan Park.

Her longtime doubles-partner is Martha Lenthe; she credits Remak for teaching her. “No one plays easy on her,” Lenthe says.

It’s easy to see why as her teammate and two opponents brag of her point-prowess. She might miss a few shots or returns, but then she’ll show-up when it matters most with a game-winning signature maneuver.

“She has a killer drop shot,” says Nancy Fisher, who partners with Pat Eoyang.

Remak shrugs it off.

“It’s all just luck,” she replies.

The ladies aren’t buying it.

“It happens too often for that,” says Eoyang. Eoyang and Remak have played together for decades, meeting through their husbands who were IU professors. Back then, there was no IU Tennis Center or courts at Bryan Park or city tournaments.

Remak stopped competing in city tennis tournaments a few years ago, and now she sticks to doubles.

Her tennis friends started a new tradition to celebrate one of her milestone birthdays (she tells them to not say the year—again with the age­—when someone slips it out) several years ago. Everyone comes together for a round-robin of tennis at Bryan Park with prizes; a great mixture of fitness, fun and friends. The tight-knit group also gets together to watch the big televised matches at Remak’s place.

“She’s an inspiration,” says Fisher.

“You’re interviewing a legend,” says partner Lenthe.

Remak downplays it all.

“Oh gosh, you guys,” Remak says, taking a sip of water.

She wants to leave the sidelines and return to the court she knows so well. When she’s done answering questions, she peels off navy warm-up pants and pulls down a white Adidas visor so she can get back to the game she loves, a game she shares with those she loves.
