Hi everyone - it's 100 days (or thereabouts!) until I run my first ever marathon which is 26.2 miles / 41 km. Am only ever going to do this once because you actually have to train for these things months in advance - who knew?!

I'm running for a great cause... the British Heart Foundation. Appreciate that everyone wants sponsoring for something these days so here is a little bit about what the BHF do:

I'm raising money for the British Heart Foundation's research and I'd be so grateful for your support. The BHF has helped halve the number of people dying from heart and circulatory disease in the UK but sadly every day hundreds of people lose their lives. It's only thanks to support from people like us that the BHF can create new treatments and discover new cures. £24 could pay for two hours of research by an early career scientist, but every pound helps so please give what you can to help me hit my target. Thanks!

Let the training and sponsoring commence!
