Things slow down when stuff is in their way. Like running through water is slower than running through air. Usain Bolt could probably run even faster in a vacuum, except for that pesky problem of needing oxygen to breathe (and an oxygen tank might outweigh the benefits of getting rid of drag by removing the air).
