Best son in the world? Eric the marathon machine pushes mum with MS along in wheelchair

Some sons go to great lengths to make their mothers happy, but maybe none more than Eric Domingo, a marathon runner from Barcelona. He pushes his mother who lives with multiple sclerosis along in her wheelchair when he goes out running. The pair recently attempted to break the World Record for a half marathon in a wheelchair but fell just short in Seville but they won't give up just yet and plan on smashing the record soon.
