How do I encourage more donations to my page?
Our top tip is to personalise your page with as much detail as possible – this includes adding a profile photo, personalising your reasons for taking on the challenge and making regular updates about your challenge and progress.
How do I join the Facebook group?

Do the milestone totals for incentives include Gift Aid?
No. All milestone figures for incentives are based on your core fundraising total before Gift Aid. Gift Aid is a bonus from HMRC that charities receive separately from your donations. While it increases your overall impact, it is not counted toward incentive milestones. The qualifying total is the main donation amount shown on your fundraising page (excluding the Gift Aid figure).
