Important information from the event organiser
All sponsorship goes directly to the Charity via your online fundraising page. At least 50% of the sponsorship target should be with the Charity 3 week prior to the Challenge. At this time, the Charity agrees to pay a fee for your place to the Organiser (similar to the Self Funding cost – or half of it for Mixed Funding as you’ve already covered half). Failure to meet the deadline may result in cancellation of your place by the charity. The remaining 50% and any extra, should be with your Charity by 4 weeks after the Challenge.
This event is organised by Action Challenge.
