Gold medals on offer: 3

Dates: Sunday 16 February-Sunday 23 February

G-force: Crews are subjected to 5-g forces when their sled corners a bend at speed

Brakeman: Sits at the back of the sled and controls the speed by applying the brakes at appropriate times

Pushers: In the four-man, two additional athletes help push the sled and then sit in the sled between the pilot and brakeman
