Meet a sport's icon making his mark at the Olympics in Paris. After the biggest grind, Andy MacDonald will represent Team GB at the grand old age of 50. This is a man who holds the record for the most X Games medals in a skateboarding discipline - the pinnacle championships of extreme sports - and he has also been named World Champions skateboarder nine times. He has even invented tricks that will feature in the Games but even for him, going to Paris is something special.
