Dubbed “My Hell of a Homecoming,” the event featured Daley rowing, cycling, swimming, and running over 270 miles from London to Plymouth in just four days.
“This has honestly been the hardest thing I have ever put my body through!” Daley posted to social media.
While Daley is an elite athlete, his “Hell of a Homecoming” was clearly a feat that required a Herculean effort from the proud husband, father, author, and activist.
“I am honestly exhausted, I don’t think my body has felt this kind of pain,” Daley told Plymouth Live after two days of the event. “I’ve never had to do anything like this ever before.”
He described the weather as “absolutely horrendous, with wind and rain” that was so bad there were periods of near zero visibility.
“I had to push up a hill for about 15 minutes earlier and I was going at two and a half miles per hour because I couldn’t push anymore,” he said.
In the days leading up to the race, Daley was definitely not shy about posting pictures of his preparations and training.
And the day before the start of the fundraiser, Daley relaxed shirtless in bed with some knitting.
But after finishing the final leg and day of his journey, with some moral support from Izzard, Daley was all smiles.
“MADE IT TO PLYMOUTH!” Daley emphatically posted after the epic race was finished.
Daley won the gold medal for Team Great Britain last year in the men's synchronized swimming 10m platform event, besting the defending champions Cao Yuan and Chen Aisen representing China by little more than a single point. It was the first time divers from China did not take first place since 2000. It was an emotional win, and Daley could be seen shedding tears on the victory podium.
“I still can't honestly believe what is happening,” Daley said at the time. “That moment, being about to be announced as Olympic champions, I was gone. I was blubbering.”
