The athlete, 48, on childhood asthma, dogs, Portaloos and the last mile of a marathon

I had asthma as a kid and still do. I started blacking out a little at the end of training runs. Then, at 14, I was diagnosed with exercise-induced asthma by a brilliant doctor who told me, “This isn’t going to stop you doing any of your sport, you’re just going to have to learn to control it.” I have inhalers in pretty much every bag.

What makes me sad? Losing people I care about – I lost my dad in 2020. And hearing stories about kids who weren’t as lucky as my daughter, who beat cancer last year. I burst into tears when the doctor gave us the initial diagnosis, but she’s been so brave. The chemotherapy made her hair fall out, which was obviously difficult for a teenage girl. But she’s bounced back so quickly.
