The first two heats of the men’s four-man bobsled final will be at 7:30 p.m. and 9:07 p.m. In the bobsled, racers have to combine brawn with agility as they work to push the sled at the start and then pile in for the bumpy ride down the hill at speeds reaching 90 mph. The pilot in the front steers and the man in the back is in charge of slamming on the brakes at the finish. The other two just keep their heads down. All four runs count for the final score. Fun fact: The sleds go so fast that the course finishes on a steep uphill to slow them down.
