Olympics idea #2 - The Octahydron

This came out of a brainstorming session my wife and I had around the other 7 ways to improve the Olympics.

In Track and Field, there is the Decathalon and Heptathalon.  There's also the Triathalon, and in Winter, there is the Biathalon.

I love combinations of sports like this, which require more than one type of fitness to excel.  To be good at these types of sports, you have to have all-around fitness.

Thinking about having 4 different Olympics, one for each season, etc. led to the consideration of having other sport multiples that people could compete in to showcase total fitness in a given area.

The "Octahydron."  8 water-related sports:

1. Swimming:  50m Freestyle
2. Swimming:  400m Medley
3. Swimming:  1500m Freestyle
4. Diving:  10m platform - best 3 of 6 dives
5. Diving:  3m springboard - best 3 of 6 dives
6. Kayak:   200m sprint
7. Canoe:  1000m
8. Surfing - whatever rules get used in Tokyo 2020

I think this would be really interesting to watch, because right now, athletes that excel at any one of those sports tend to have a similar musculature and body type.  So what would an athlete look like if they did well at all those different sports?

Also, it's not so far-fetched to think of a person doing canoe, kayak, and surfing - sports that require the use of aparati, because in the other multi-sport groups, apparati are used as well.  Cross country skis and rifles, for example.
