Big Bryan vs the London Marathon

I discovered running through my son - who insisted I run our local Parkrun (Hilly Fields!) with him a few years ago. It was a complete nightmare, but we returned the following week and we've both been running ever since. I never thought I'd be a runner - but there's something about it that feels so beneficial to my mental state. I never thought I'd run a marathon either - but here we are! I'm nervous, but excited. I know that if I put in the training I'll get across that finish line. This is the big one!
