Flawed Hero midnight marathon

I've ambitiously signed up to the Flawed Hero midnight marathon, starting from Broadway Cinema in Letchworth at 12pm (midnight) on Sun 27 April and taking in 17 loops of the garden city. But it's for an excellent cause... Pancreatic Cancer UK, which is hard to diagnose and often not found until an advanced stage. I'd be exceptionally grateful for any sponsorship you can offer.
