Challenge Events
Run 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 and swimmers:
- No entry fee (this is unusual).
- We count legitimate Gift Aid towards your fundraising target (this also seems to be unusual).
- There's a matched giving option which can almost double 🎁🎁 the amount you raise.
- 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.

Date: April 2027, likely same day as the TCS London Marathon
We don't actually have charity places for this 66 mile (106 km) cycling event 🚵, but we include it here because it counts towards the London Classics medal 🥇, so people sometimes ask about it. It's best to sign up for their mailing list here and apply for a general entry place. You're welcome to fundraise for Whisper, if you like! 💖

Various dates and locations.
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! 💖
