My name is Ollie. I am 10 years old and my Grandad Nick has a condition called Lewy Body.

I have set myself a challenge of walking, running or cycling 500 kilometres over the course of this year to raise money for the Lewy Body Society. There is no cure for Lewy Body at the moment, but I am hoping that by fundraising for the charity I can make more people aware of the condition and help raise money for research into it.

I think I can do the distance, but it's going to be a challenge to do it consistently all year as I will need to be completing almost 10km every week for the whole of 2024!

Anybody who knows me or my Grandad, please don't tell him I am doing this just yet. I'm going to surprise him with it later.

The Lewy Body Society was founded in 2006 to support research into Lewy body dementia and to raise awareness of the disease. They aim to educate the public, the medical professions and those in decision-making positions about the disease, which unfortunately is still not well known.
