It wasn't through choice that I became a mum at 36. I wanted to be a young mum but things never worked out for me.

Now I look back and think if I'd spent more time enjoying myself instead of crying into my pillow over men, my 20s would have been fabulous!

I eat quite healthily normally but, like everyone, have relapses and give in to the odd cake.

I did the Kilimanjaro climb a few years ago, then the six-day trek to Machu Picchu in Peru so this bike ride to raise money for Great Ormond Street seemed like the next big challenge.

At weekends, I've been going on long but steady-paced four-and-a-half-hour bike rides.

Much as I loved doing 'The Big Breakfast,' it almost became automatic. I need something to keep my brain ticking over, something that I have to concentrate on.
