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.

I mean, I'm lucky because I've slimmed down, but the last thing I was thinking about was losing weight.

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

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'd got to that age when I was out on a date with a guy and I would be thinking: Don't mention your age, don't mention that you want a child - because they would just run out the door.

Everybody thinks if you do one thing, you can't do something else. So I like the fact that I can be versatile if I want to.

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