Challenge Events
Run, ride or swim with Whisper's Magical Children's Hospital 🏆
As a high-impact charity, Whisper offers you and your supporters a cause worth supporting, where even small donations can be life-changing ✨
Things we normally offer our runners, riders and swimmers:
- No entry fee (this is unusual).
- We count legitimate Gift Aid towards your fundraising target.
- If you have to drop out for some reason, we can usually offer you a place the following year and credit you with your fundraising; conditions may apply.
- The places and related expenses are funded by a Whisper supporter as a thank you 👏🏼 to YOU for taking part. Your supporters aren't paying for your place.
We currently have charity places for the events listed below. If the event 🏆🏊🏼🪂🏃🏼 you are interested in is not shown, feel free to contact us; for some events we can get charity places, for others it's best if you apply for your own non-charity place.

We don't currently offer charity places for these popular assault course events. If you join their mailing list towards the end of the year, they will often give very good discounts on places for the following year. You're welcome to fundraise for Whisper, if you like! 💖
