How I train: Andy Donaldson

Andy is a Scottish-Australian marathon swimmer and a three-time world record holder with records including the fastest time to complete the Oceans Seven marathon swim challenge, and the fastest swim across the Cook Strait

Andy, which of the seven oceans was the hardest and why?

For me, the Tsugaru Strait presented the most difficult challenge. As the final leg of a year-long campaign, I carried a considerable amount of physical and mental fatigue coming into it.
