A gym in the heart of San Francisco will close later this year, the company announced.

After 29 years in business, the 24 Hour Fitness at 100 California St. will close its doors for good on Dec. 29. The location is one of two in Downtown San Francisco.

“Our 24 Hour Fitness location on 100 California St. in San Francisco will be permanently closing on Dec. 29, 2023,” 24 Hour Fitness said in a statement. “The nearby 24 Hour Fitness gym at 45 Montgomery St. will remain open to service 24 Hour Fitness members, as will our convenient location on 1200 Van Ness Ave.”

Gym memberships at the California Street spot will automatically transfer to the nearby location on Montgomery St., according to 24 Hour Fitness. The company also manages a gym at 1645 Bryant St. in Potrero Hill and in Ingleside at 1850 Ocean Ave.

People on social media mourned the loss of the Downtown gym.

“Bummer. The damn near 200-degree sauna and whirlpool were both insane and amazing,” one person opined in a Reddit post about the closure.

The company, which has nearly 300 locations in the U.S., said the facilities at nearby locations will continue to serve members.

“The expanded amenities at both Sutter Montgomery and Van Ness clubs, like the GX24® studio, sauna, whirlpool, steam room, and more will be a strong offering to affected members as they continue on their fitness journey with us,” 24 Hour Fitness said.

In 2021, 24 Hour Fitness filed for bankruptcy and closed 13 locations, with the CEO blaming Covid for the drastic measure.

The gym’s closure comes as McDonald’s in the city’s Financial District shuttered after nearly 30 years in business. The restaurant’s operator blamed office vacancies and fewer visitors Downtown for the closure.
