On 12 February 2008, on his 30th birthday, Jones and his Blue Peter co-presenters climbed the highest peaks in each constituent country of the United Kingdom, starting with Slieve Donard in Northern Ireland, followed by Snowdon in North Wales. The following day, having travelled overnight by coach to the Lake District, they climbed Scafell Pike. They were then to be transported to Scotland by helicopter to climb Ben Nevis, but were unable to do so because of problems with the helicopter, forcing them to land in Oban. They succeeded in climbing the mountain the next day. This challenge was in aid of Sport Relief 2008.
