These things are just about the most catholic (I don’t mean the religion) events going. You get all sorts. No need to be in a club or have a license or anything like that.
Mostly it’s weekend warriors having a laugh. There’s probably two or three teams out of what, 3-400 men’s teams trying to win it. The next 50 or so will be trying to do as well as they can, everyone else is just out for a laugh.
You need to do at least two laps each according to the rules, but no-one really cares that much tbh. Most rules transgressions get overlooked by the officials anyway unless you are really being an arse or are in it to win it.
You only need to be fit enough to do your two laps, really. You see loads of beginners who are loving it to bits despite being slow; you also see one or two looking like thunder because they’ve been duped into it a bit 🙂
It can get tough at 3am in an unrideable mud fest but it’s one of those things – you’re in the situation where you have to really dig deep, but it’s in a completely safe environment. When you’ve struggled and come through, you’ve fought the mud for three hours and made it, the sense of achievement is hard to describe. And people laugh about it afterwards, no matter how grim it ends up being 🙂
