What is the part of your job that people would be surprised is most of your job?

And now, what are those of us who are elected public officials supposed to do? We call ourselves "public servants" but I'll tell you this: We as public servants must set an example for the rest of the nation. It is hypocritical for the public official to admonish and exhort the people to uphold the common good if we are derelict in upholding the common good. More is required -- More is required of public officials than slogans and handshakes and press releases. More is required. We must hold ourselves strictly accountable. We must provide the people with a vision of the future.

I have a bunch of rules for myself. You stop at every village, you ask what the situation is like between this village and the next village, you look for fresh tire tracks. If there are any land mines in the area, then you always want to make sure you go on fresh tire tracks to reduce the risk of mines. You carry a certain amount of money so that if some soldiers with guns want to rob you — no fuss — you give them a decoy wallet or some other money to make them happy, and you just learn to kind of be soothing with unpleasant people.

Treat writing as a job. Be disciplined. Lots of writers get a bit OCD-ish about this. Graham Greene famously wrote 500 words a day. Jean Plaidy managed 5,000 before lunch, then spent the afternoon answering fan mail. My minimum is 1,000 words a day – which is sometimes easy to achieve, and is sometimes, frankly, like shitting a brick, but I will make myself stay at my desk until I’ve got there, because I know that by doing that I am inching the book forward. Those 1,000 words might well be rubbish – they often are. But then, it is always easier to return to rubbish words at a later date and make them better.

Those lactate sessions were the worst. I'd be in a lab on a turbo trainer and I'd do four 30-second efforts at 100% effort. It sounds so innocuous but the difference between 99% and 100% is huge. You can finish at 99% and you'll be hurting but if you push a tiny bit more – and that's the bit that makes the difference to your training – your legs just grind to a halt. It's like your engine is seizing up. My coach would unclip my feet and pull my leg over the saddle so I could just slide off onto a mat and curl up in a ball.

We were training 12 to 15 times a week, 50 weeks of the year. I think sometimes people see you compete at the Paralympics or other amazing places around the world and think that is what you do all the time. There is an element of that, but a lot of it is just really boring and repetitive. The vast majority of your time as an athlete is spent on the road or in the gym.

For a photographer — it’s like actually taking a picture is like five percent of what I do. And the rest is research, reading, contact, setting things up, making contact, getting access, making people feel comfortable, doing the reporting, doing the interviews, getting the captions. It’s not getting there physically, the logistics on the ground. I mean, literally, taking a picture is the easiest part of my job.

I looked straight across at the clock and I was disappointed with the time. I should have run under 49 and I didn't. And I knew I had a lot more in me.
