On the 7th of September I'll be cycling the longest distance I ever attempted to raise money for a charity that is very important to me. With friends and colleagues from Dyson we'll be cycling 200 km (125 miles) from Malmesbury in Wiltshire to Abergavenny to tackle the infamous Tumble climb (400m ascent over 5.1 km, average 8% gradient). Then cycle all the way back to Malmesbury! This year we're hoping to raise more money and exceed £100,000 total for the charity. Any money you donate will be matched by Dyson. Thanks for your help.

We are the UK's leading dementia research charity, dedicated to causes, diagnosis, prevention, treatment and cure. Backed by our passionate scientists and supporters, we’re challenging the way people think about dementia, uniting the big thinkers in the field and funding the innovative science that will deliver a cure.
