This Saturday and Sunday Jonny is running his first ever ultra-marathon for charity. He will be running 50 miles at Bear Mountain. The cause he is raising money for is: Jonah's Just Begun which is a charity raising funds to help find a cure for Sanfilippo Sydrome. This is a very rare condition that causes brain damage, bone deformities, organ failure and death, often by their teenage years.

Crowd Rise is the way to donate if you wish. Jonny is also on Twitter @jonnyjlm

Thank you.
