World Record-holding Ultra Marathon Swimmer

Andrew "Andy" Donaldson is a British-Australian marathon swimmer. He holds three world records, including the fastest time to complete the Oceans Seven and the fastest swim across the Cook Strait – the waters between New Zealand's North and South Islands.

Andy was introduced to Precision Fuel & Hydration in 2022 when embarking on his mission to complete the Oceans Seven, the world's toughest channel swims, within a year. He incorporated their gels into his marathon nutrition plans, and they have been a pivotal part ever since.

Away from sport, Andy is a Chartered Accountant and a dedicated advocate for mental health. He was voted Man of the Year and Performance of the Year in the World Open Water Swimming Association awards for 2023.
