What are your main options for collecting sponsorship?
Paper sponsorship forms
The traditional method. Participants take home a printed form, fill in sponsors' names and amounts, collect cash or cheques, and bring it back after the event.
It requires minimal setup. You design, print and distribute the form, and plenty of groups still do it this way. But it has real costs once the event is done: cash is harder to collect, organisers spend hours reconciling what came in, some families never return the form, and sponsors who intended to give but didn't have cash to hand often don't give at all. Gift Aid is harder to claim. Reminders are manual. The post-event admin often takes longer than the event itself.
A single group donation page
Some groups set up a single online donation page for the whole event, share the link on the school newsletter and in the parent WhatsApp group, and ask people to give.
This is more convenient than paper forms, but it loses something important. Supporters are asked to donate to the event or the school in general. There's no personal connection. Research into UK peer-to-peer fundraising consistently shows that people give more when they're sponsoring a specific person they know, not a general cause. A message saying "please donate to our fun run" raises a fraction of what "please sponsor Jack for his fun run" raises.
A single group page also limits your reach. The organiser shares it, some parents share it, a small circle of people see it. With individual sponsorship pages, every participant shares their own, and every family brings a different network. Instead of one campaign, you have 100 or 200 small ones running at the same time, reaching people you'd never reach through a single link.
Individual sponsorship pages, one per participant
Each participant gets their own page. They share it with the people who know them. Sponsors give directly to that page. The total rolls up for the organiser to see.
This is the approach that consistently raises the most, because it turns every participant into a fundraiser. Instead of one shared link that the organiser promotes, you have 80 or 100 or 200 participants each doing their own asking. The reach multiplies. The personal connection does the work.
The practical question is how to set this up without it becoming a spreadsheet and admin nightmare. That's where the right tool matters.
Online fundraising platforms designed for charities
General online fundraising platforms are built for registered charities running individual campaigns. They handle donations well. But they're not designed for the specific flow of a volunteer-led sponsored event: entry sign-up, participant lists, entry fee collection, individual sponsorship pages per participant, and live totals for the organiser. You can make them work, but you'll be combining them with a separate entry or ticketing tool, which creates friction for participants and extra work for you.
