For the Midlands based peeps, I got some stuff in the post this morning about a 5k and 10k run in Sutton Park for Cure Leukaemia. It's just 13 quid to enter the 10k, and I'm planning on doing it as a sharpener for Little Beaver OD, 2 weeks later.
There's supposed to be some info up at www.cureleukaemia.co.uk, although it doesn't seem to have been updated yet.
