Usain Bolt holds the world record at 9.69 seconds for the 100 meter dash. Usain Bolt holds the world record at 19.30 seconds for the 200 meter dash. Michael Johnson holds the world record at 43.18 seconds for the 400 meter dash. So I would say Usain Bolt.
lost of practice at the track your going to run fast on
the difference is that in a shuttle relay, you run back and for(e.g. you run 100m to the next person and they run back to where you started, where the next person is waiting e.t.c.). A circular relay is around a track e.g. a 400m track you each run 100m going round the track. hope this has helped.
