We use to run a 24 hour race with FUD Racing in the Superstition Races, It does not look like MDR is doing them. Have you heard or seen any 24 hour races where you see how many miles you can go in a time frame instead of how much time it takes to cover a certain amount of Miles.

I don't know if anyone in the off-road world who has a 24 hour race like Fud use to run and am not sure whether MDR took over the role of organizing that race. Either way, it'll never be the same without Fud.
