Run 31 Miles in August 

This August, lace up and help rewrite the story for brain tumour patients.

Join our Run 31 Miles in August challenge and turn your miles into hope for those affected by the biggest cancer killer of children and adults under the age of 40.

Whether you run, jog or even walk, your 31 miles will power vital research and raise awareness of a disease that still receives just a fraction of the funding it so urgently needs. And along the way, you’ll be boosting your own fitness and wellbeing too.

31 miles. 31 days. One powerful reason.

Run a mile a day, spread your distance across the month, or take on a few longer runs – this is your challenge, your way. However you choose to approach it, every mile you complete brings us closer to better treatments and, ultimately, a cure.

Make your miles matter 

 • Start your mornings strong with a quick jog before the day begins
 • Unwind with an evening run in the summer light
 • Build up to a weekend challenge and tick off bigger distances

However you go the extra mile, you’ll be joining a community with one shared goal: to beat brain tumours.
