It's a subjective thing that can't really be viewed in terms of how fast people go, it's about effort, and intention, I think it was on the south downs double website that I read a thing that sums it up:
"the idea of this is to ride the route as fast as you can"
If as fast as you can is 31 days for whatever reason, 100% good on you, and well done, but, if you do it in 31 days cause you're chilling, partying whatever, treating it like a cycle tour, then you've done a bit of a disservice to the race, as that spot could have been taken by someone who treated it as a race.
