I’ve competed in many running races, and I’m not sure if they even have written rules. Presumably they do, but I’ve never read them. You don’t need to, everyone knows what a race is.

Likewise, I use GPL software daily, for a living - doesn’t mean I’ve ever read the license.

It depends on the race, sometimes there are rules that might surprise you. One that I recently signed up for has pretty specific gear requirements for 10k/21k/42k/60k. Trail races can have strict rules as well, like the type of compass and nutrients you need.
