In a moment of madness 6 months ago, my boyfriend and I signed up for the Thames Path Challenge on the 10th September; a 100km charity walk from Putney to Henley, that most people aim to complete within 24 hours. 10 days prior to this, my boyfriend fell off a climbing wall and badly sprained his ankle, and I was forced to accept that if I was going to be undertaking this epic challenge, I would be undertaking it alone.
