Make a Real Difference – How your participation will support Rennie Grove Peace
Behind the thrills, spills and inflatable hills lies a powerful purpose: to raise funds for local hospice care. Everyone who takes part for Rennie Grove Peace is challenged to raise at least £200 in sponsorship per person – enough to fund five hours of specialist nursing care wherever it’s needed. Which could be in our Inpatient Unit, at a patient’s home or in our Living Well programme.
Participants who raise at least £250 will receive a free Rennie Grove Peace t-shirt.
Heather, from St Albans, has been visiting Grove House for Living Well services since she was first diagnosed with breast cancer in 2015.
Our Living Well programme is offered free of charge to people who are living with a progressive life-limiting illness. It is designed to help people understand how to live well with their illness so they can maintain independence and enjoy life.

“I used to think hospice care was about old people sitting around in chairs and being sad, but that’s not how it is at all. I have been able to access everything from chair yoga and wellbeing classes to complementary therapies and the Living Well programme. There are people of all ages who access the different services and it’s an upbeat and cheerful place.”
For teams & businesses
Pick Your Distance
Bounce your way through the course at a distance that suits you! The classic 5K is two laps of inflatable fun – but if you’re feeling bold, you can go for 10K or even the ultimate 15K challenge. Want to keep it light? Try a single 2.5K lap.
Every option is packed with epic obstacles and non-stop fun. Run, jog, or walk – it’s all about the laughs, not the lap times! And while you’re having a blast, you’ll also be helping raise funds for a great cause – fun, fitness, and fundraising all rolled into one unforgettable day!
