He's running for a charity called JCF (Just Children Foundation). It is a Christian based charity which supports orphans living on the streets by providing care, shelter and education. There is no government help for these children and I'm sure people are aware of the current situation in Zimbabwe.
As he grew up there, he felt he would like to support this charity and raise some much needed funds to make things a little better for some of these orphans.
If anyone can spare a little (no matter how small) to support this worthy cause, he'd be very, very grateful.
TIA
