Davina McCall has admitted her marriage was in trouble before her Sport Relief challenge.
The TV presenter, who ran, cycled and swam 500 miles from Edinburgh to London for the charity last month, has confessed her and husband Matthew Robertson were in a "tough place" in the lead-up to her challenge.
She told the Daily Mirror newspaper: "We had a really difficult six months. Matthew's dad was ill, I was doing the challenge and he'd hurt his shoulder.
"We weren't arguing, but we had both been in kind of a tough place. Now we are here and we've been on holiday.
"Getting through stuff like that makes the next step better. If you never give it a chance to get through something difficult, you never get to that step where you think, 'I know you, and you know me.' "
The 46-year-old star and Matthew, 45, have had marriage counselling in the past and Davina admits if they were younger and not married they probably would have called time on their 14-year union this year.
She explained: "When you're in your twenties and you have a tough six months then that's a break up. But when you're married it's nothing. You always have to think when you are in a relationship that if you have a tough six months then it's nothing in the grand scheme of things."
Davina was pulled from Lake Windemere in Cumbria when she became exhausted during the challenge and Matthew, who runs an adventure business, drove seven hours to be by her side because he was so concerned about her.
She added: "Matthew was worried when I came out of the water. When he found me cycling and he laughed and said, 'I can't believe you are now on a bicycle.' I'm sure he wanted to rescue me."
