Stair climbing is a amateur sport. You race up a very tall building and try to get the best time you can. The Willis Tower has been used for multiple stair climbing races. It is 103 stories, 2,115 steps! Think of trying to run up that building. Stair climbing is used a lot to rase money for things so anyone can join the race.
