Does anyone out there have any experience with organising a fitness event? I'm think of putting together a fitness type obstacle challenge in support of type 1 diabetes over here in the UK but don't really know where to start.

I need to know if you need money behind you for insurance purposes etc, would it cost me anything? do I need sponsorship to get the ball rolling? so many things to think about but again not really sure of where to start.

Can anyone advise?

Thanks
