Story
This will be my fourth marathon, but the first time I've run any other than the London Marathon. I'm looking to run a new PB of 3:45, but we'll see what happens on the day.
I'm became aware of the JoiningJack charity when some high-profile sportsmen were talking about their support for the charity, including some Wigan Warriors rugby league players such as Sam Tomkins, the Tour de France winner and Olympic champion Bradley Wiggins, and a host of others.
The charity JoiningJack has the aim of finding a cure for Duchenne Muscular Dystrophy.
