Sarah Thomas has become the first person to swim the English Channel four times without stopping.
Thomas completed the amazing feat this week.
She began the epic challenge in the early hours of Sunday and finished after more than 54 hours.
Ms Thomas – who completed treatment from cancer in 2018 – dedicated her swim to “all the survivors out there”.
The swim was supposed to be 130km but because of strong tides Ms Thomas ended up swimming closer to 210 km.
Ms Thomas is from Colorado in the United States.
