“I’ve done it numerous times… but taking on a challenge like that and meeting in Paris is magical.”
His wife Julie said she was “so proud”.
“It’s just fantastic. It’s a huge challenge and I think 90% is your mental state,” she said.
“I think Geoff being a professional sportsman, I think he just has that drive in him, no matter what’s happening to your body, you just get on with it.
“I think he doesn’t really think about what’s going on at the time, he just pushes on for the charity really, for the cause.”
Thomas, who was appointed an MBE in 2021 for his work raising money for cancer charities, said everyone that took part should be proud of themselves and what they had achieved.
“I am proud of them and I’m proud of the charity and that’s why I carry on doing this and oddly, even though I was the most unfit I’ve been taking on this challenge, it’s inspired me even more than any other.”
