It all really depends on the race and total elevation gain. for every ultra there is essentially 2 races, your pros who will be so far in front of everyone else its not even funny and than your amateurs you could put it. main goal obviously finishing and than a lot of ultra runners sub goal is to finish a race in under 24hrs which is extremely difficult (kind go the golden goal with the history of the sport). Anyone who even finishes a 100mi is a complete animal no matter the time. I have never done one but crewed for a couple ultras and those 100miler guys are absolutely insane.
