<p>Hello all, I fancied a challenge for the new year and figured an ultra-marathon would fit the bill! I'm taking part in the 100km (62.5 mile) London to Brighton Challenge in May. Gonna try and run the whole thing - blisters permitting - from Richmond to Brighton hopefully in around 10 hours.</p> <p>I am doing it for Macmillan Cancer Support and would like to raise as much as possible for them so come on people, dig deep!</p>
