passing, same as any other sport.
Runners run on a track.
They run.
Shorter track
Runners 1 and 3 are at the start, runners 2 and 4 are half-way (100 metres) along the track. They finish at the start.
To form a 4-person relay team from 8 track runners, we first choose 4 runners from the 8, which can be done in ( \binom{8}{4} = 70 ) ways. Then, we can arrange these 4 runners in ( 4! = 24 ) different ways. Therefore, the total number of arrangements is ( 70 \times 24 = 1680 ). Thus, there are 1,680 ways to arrange 8 track runners on a 4-person relay team.

=Jesse Owens is one of the fastest people in the world.=
Nope, only track runners. Yes there are crocodiles in Kenya.
He trained Olympic runners at the Joe Carmody athletics track.
How track works is they call out the next events and the runners start on the starting line. A starter gun is shot and the runners run a specific number of laps. The runner who beats the rest wins the race.
for keeping track of marks and stuff
my advice to you is study and use notecards
