Just for fun, some alternatives to Olympic sports:

1. Instead of high-jumping over an ever-raising bar, they have the athletes
just jump over nothing, and figure out a way to measure how high they all
jumped.
2. Standing high-jump.
3. Swimming races in which the swimmers have to splash as little as
possible, like the way the divers have to splash as little as possible.
4. An multi-race event with two races on different days, similar to a
pentathlon. One race is 100m spring, and the other race is a marathon.
They come up with a mathematical way to have the two races equally weighted.
5. A multi-sport event involving a combination of extremely disparate
sports. For example, dressage, swimming, tennis, gymnastics, and high-jump.
6. Same multi-sport event as above, except no one knows what the sports
will be ahead of time. Each day's event is drawn out of a hat the day
before. All athletes do the same sports, but no one knows ahead of time
what they will be.
