Well it is in the name, endurance RACES. It is a race not a test of pure endurance. To test pure endurance you would need to start running or walking or swimming at your own pace and continue till you drop to the ground and the one that can do that for the longest would have the best endurance.

You're describing the backyard ultra. The male record is 450 miles over 4.5 days. The female record is 308 miles over 3 days.

Yes kind of, they still have a minimum speed people need to adhere to.
