Meet the man who has spent the last year taking on Europe's most gruelling sporting challenges - including scaling Mont Blanc. Jack Harrison, 27, started his quest in June last year - which has seen him journey from his home in York across the mainland continent. He simply searched on Google for 'The UK's toughest races' or 'The world's toughest races' - and settled on climbing the 15,780ft Mont Blanc. And after completing that task he realised then he had developed a taste for the extreme - so spent the next year trying others. Since tackling Mont Blanc Jack has also been to the Artic Circle and done cross-country skiing in Sweden - as well as taking on a number of UK challenges. The helicopter engineer, has used his own income to fund the trips.
