South London hills

I think I'd need to strap my kneecaps on rather thoroughly to attempt either of those, and I'd still end up walking most of it.

Would I be allowed to attempt it with gears?

i think that all should be included unicycle even if you want. all we really need to make sure of is that the hill decided upon is not so severe that it scares anybody off and there is a public house very nearby. oh and the dates calendar should be looked at so that it doesnt clash.
