You would have thought he'd had enough of the water.
But record-breaking swimmer Ross Edgley has become the first competitor to sign up for next year's Red Bull Neptune Steps challenge in Glasgow.
It comes less than a fortnight after the 33-year-old became the first person to swim the 1782 miles of seas and open water around mainland Great Britain.
Ross's epic feat around Britain took five months in which time he didn't set foot on dry land.
Ross, who lugged a tree trunk around the Caribbean for a 100km swim last November and rope-climbed the equivalent height of Mount Everest in just 24 hours back in 2016, is excited to return to Maryhill Locks for the second year in a row.
He said: “The Great British Swim was 1,782 miles of swimming, completing 2.3million strokes across 157 days at sea, through dolphins, whales and stunning sunsets.
"But without doubt the best mile I ever swam was at the very end when 400 swimmers braved the cold, British, winter waters and swam the final mile with me.
"The atmosphere in the water was indescribable. This is why I love adventure swimming and the only other event I’ve experienced that comes close is Red Bull Neptune Steps.”

The UK’s toughest open-water adventure race will return to Glasgow for the fifth year in a row on Saturday March 23.
Tickets will go on sale on November 20.
A record 600 endurance athletes braved the three-degree swim-climb race at Maryhill Locks in March.
Last year, Scottish water polo international Jennifer Davis was victorious in the women’s race, claiming her second Red Bull Neptune Steps gold, whilst Welsh international swimmer Dan Jones triumphed in the men’s edition in his first ever open-water swim.
The race is open to men and women aged 16+.
