He has won fourteen medals at the FIL World Luge Championships with twelve golds and two silvers. Loch's men's singles win in 2008 made him the youngest world champion ever at 18 years old. He is the youngest Olympic Gold Medalist in men's luge history. As of 2022, Loch is a triple Olympic gold medalist.

A luge is a small one- or two-person sled on which one sleds supine (face-up) and feet-first. A luger begins seated, propelling themselves initially from handles on either side of the start ramp, then steers by using the calf muscles to flex the sled's runners or by exerting opposite shoulder pressure to the pod. Racing sleds weigh 21–25 kg (46–55 lb) for singles and 25–30 kg (55–66 lb) for doubles. Luge is also the name of an Olympic sport that employs that sled and technique.
