In July 2022 Lee started the Triathlon of Great Britain by attempting to swim the English Channel under the rules of the Channel Swimming Association, but was beaten by the conditions in the Channel. Undeterred he carried on with the triathlon, travelling to Land’s End as quickly as possible and started the cycling phase. Lee cycled from Land’s End to the base of Mount Snowdon, climbing the highest mountain in Wales, and then cycled on to Scafell Pike, the highest mountain in England. Lee managed to summit Scafell Pike, but could go no further. Throughout the cycle and mountain climbs, Lee had been trying to manage the toll taken on his stump by the constant rubbing within his prosthetic leg. By Scafell Pike, the rubbing had deteriorated to open cuts that caused his stump to swell. The open wounds and swelling made it impossible to wear his prosthetic and meant he could go no further.
