So, if you’re looking for something fun and different to do this year, Inflatable 5K is calling your name!

Not only will it take you back to your childhood bouncy castle days, it will also help get you fit and create lasting memories with your friends or colleagues.

And if you choose to raise money for Ronald McDonald House Charities UK, you’ll be helping thousands of families stay close to their sick child in hospital.

Why fundraising as a group makes a difference

Fundraising as a team helps keep motivation!

With a larger group of people, you can help to educate people across the UK about what Ronald McDonald House Charities UK does for families.

The more team members, the bigger the fundraising pot, and the more families are helped!

Not only was it so much fun to take part in, it also brought me closer to my colleagues. One dream, one team!

– fundraiser, Jake.

Impact families across the UK

As well as doing something fun with your family, friends or colleagues!
