Take on the challenge, support life-changing research!

Want to get spooky this Halloween? Then this is the perfect challenge for you. Dress to distress and take on the 10km walk with the PCR Events Team - or push yourself on the half or full marathon walk (if you dare...)

Choose your distance, gather your bravest guys & ghouls to make up a team – or go it alone if you dare and meet up with other chilling challengers. The creepy dungeon keepers at The Oval start & finish will meet, greet & shock. Once you escape there’s ghostly looped routes, with zombie rest stops, and if you manage to get back in one piece there’s a macabre medal, a glass of the Devil’s fizz, some horrifically delicious hot food & drink – and a souvenir bobble hat to ward off the spirits as you head off.

Eurydice, Amy and Ellen from the PCR Events Team are taking on the horrors of the 10km challenge – do you dare to join them?

Impact of Fundraising

Your fundraising helps us to support our research and ultimately transform lives. We could not continue to fund our research without you, and without our research we cannot achieve better outcomes for men with prostate cancer and their families.

Our research

We currently fund fourteen research projects, all of which aim to develop more effective treatments for and better understandings of prostate cancer. Following our ecosystem report, we are determined to fund projects that explore current gaps in knowledge and treatment to move the field forward and reach new and better treatments sooner.

Find out more about our specific research projects in our research area.

Our scientists

We fund scientists across the UK at all stages of their career. We care about the barriers faced by researchers and recognise the importance of nurturing and encouraging innovation and collaboration, to ensure that research is moving as effectively as possible to reach better outcomes for patients sooner.

By fundraising for us, you are supporting scientists at all stages of their research journey and ensuring they are treated with respect, offered flexibility and given the support they deserve.

You can find out more about our scientists in our research area.

Patient stories

We listen to patients and fund the research that will lead to outcomes that matter most to them, so that our research is entirely patient-focussed. By supporting PCR, you are supporting patients who are sharing their stories and experiences and helping to fund the research that matters most to them.

Find out more about our patient voice panel and hear from patients who have been impacted by PCR’s work.

Where your money goes

With your support, we will provide scientists with the space, flexibility, and environment that helps turn great ideas into successful treatments.

How much could you raise for our PCR scientists? Did you know that –

£73 would fund materials to grow a cell colony.

£250 would fund 6 months of essential lab consumables.

£1,200 would fund a box of new antibodies to test.

£10,000 would fund a live imaging microscope camera.
