Charity fundraising ideas

Options
Hi,

Part of my motivation to get fit is I have signed up to a 4 day trek in Peru along the Inca trail - and the fitter you are the more you enjoy it (so they say).

The other half and I need to raise over £6000 to do this (for a local Childrens Hospice - Acorns). We have until October

Just wondered if anyone has any ideas of fundraising events.....
