Why does sponsorship raise more than entry fees?
Notice what happens when you change the sponsorship number. Doubling the average sponsorship per participant doesn't quite double your total, but it gets close. That's because sponsorship is doing most of the lifting.
Entry fees are useful. They cover the basics, give the event a sense of commitment, and bring in a few hundred pounds before anyone has done anything. But the big multiple comes from sponsorship, and from giving every participant a page they can actually share.
The most common missed opportunity we see is groups putting up one donation page for the whole event instead of giving each participant their own. A single QR code at the gate raises a fraction of what individual sponsorship pages raise. The personal ask, please sponsor Jack for his fun run, works in a way that "donate to the sponsored walk" doesn't.

Common questions
How much can a school fun run actually raise?
It varies with participant numbers and how sponsorship is collected. A primary school of 200 children with individual sponsorship pages might raise £5,000 to £8,000 in total. The calculator above is a useful starting point. Change the numbers to match your situation.
Is £35 a realistic average sponsorship per child?
It's the mid-range we've seen with individual sponsorship pages. With paper forms and cash, the average is usually much lower. £10 to £15 is more common. The personal share-link makes a real difference because supporters can give in seconds when they're asked, instead of promising cash later.
Do I need to charge an entry fee?
No, but a small one helps. Entry fees cover the basics, give the event a sense of commitment, and bring in a useful base amount before sponsorship is even counted. Most groups charge somewhere between £3 and £8 per participant. Some skip the fee entirely.
What does it cost to use fun-run.co.uk?
A small percentage on entry fees, plus the usual card-processing charge. Sponsorship goes to your group in full. Full pricing details are on the pricing page.
Can I use this for events that aren't fun runs?
Yes. The maths is the same for sponsored walks, colour runs, swims, readathons, danceathons, skipathons, school-laps challenges and most other formats. The activity changes; the way sponsorship works doesn't.
