(AP) — Joey Mantia, a three-time world champion who won a bronze medal at the Beijing Winter Olympics, has retired from speedskating at age 37.

Mantia announced the end of his career in a post on his new Instagram Threads page. He took last season off to deal with back issues, hoping the time away would allow him to heal, but decided it was time to hang up his skates.

Mantia, a native of Ocala, Florida, was a multiple world champion in inline skating who made the switch to ice in 2010. He qualified for the the first of three Olympics at the 2014 Sochi Games and finally earned his first medal, a bronze in men’s team pursuit, at Beijing last year.
