I have found out from my Dad that there is going to be a unicycle marathon on the 14th of June in Foxton, Cambs (just south of Cambridge).
It’s a charity event raising money for the Stroke Association and Addenbrokes Neurological Critical Care Unit, there’s a website with the details here, and also a thread about it on the UK unicycle forum with a bit more info.
According to the thread in the other place there are only 4 riders signed up so far, and a few runners and cyclists also.
I’ll be going, as unicycle marathons are few and far between so seems silly to miss it! Anyone else up for it?
