Warren loves a large-scale challenge, having canoed the Thames and cycled the length of the country in the past. Following the same pattern, he’s doing a half Ironman. Open-water swimming, cycling and running. It’s full on. 70.1 miles broken down as an open water swim in the sea of 1.2 miles, a 56-mile cycle ride and a 13.1 mile run to finish it off. He’s just informed us he’s got his first swimming lesson this week……an ironman in armbands?!
