OK, just watched it. Young Lewis travelled to the IOM each year on his own, in a van, with his bike in the back. He became a race marshall early on. I didn't get to speak to him, as, tragically, he was killed, not long after we arrived at the campsite. Other people on the site however, had befriended him, and spoke very highly of him. Well done to his mother, who gave permission for this to be shown, and spoke very well. Definitely makes you think.
