Here's Bpositive founder Jonjo Rooney with The Sun fitness columnist Zac Taylor as Zac prepares to take on the London Marathon tomorrow for Bpositive. Through raising funds and awareness for our charity, Zac is helping us reach out to more people affected by acute leukaemia and ensure that they get the support they need. 

We all wish Zac all the best as he prepares to pound the 26.2 miles through  London and we couldn't be more proud that Bpositive will be represented amongst all the other charities as the eyes of the world will be on the Capital city this Sunday.
