I’ve done it. It's February and I’ve signed up to cycle 100 miles on July 30th in aid of the UK breast cancer research charity, Breast Cancer Now.

I’d applied for a place on the “Prudential Ride London-Surrey 100” via the public ballot. I have a good few friends who’ve done this ride in the past and I really fancied giving it a go. It’s been described as “cycling’s version of the London Marathon”. I was adamant, though, that I’d only do it if I got a place in the ballot. I found out earlier this month I didn’t get one.

There were two reasons I didn’t want to do the ride for charity. First, I’m less than a year out of treatment for breast cancer – my one-year anniversary of finishing my hospital-based treatments is on February 26th – and I wouldn’t want people to sponsor me because they felt sorry for me or because they somehow felt obliged to. Second, I felt it was too soon emotionally. I’ve been doing pretty well at “moving on”. The fear that my cancer will come back one day and ultimately finish me off still lurks there in the background, but I’m managing things well at the moment and I’m in a good place on that front. There are hundreds of worthy causes out there but I knew that if I did the ride for charity, I’d have to do it for an organisation that focused on breast cancer research. That, I felt, would plunge me right back into a world that I’m working hard to move on from.

But then the other night I was flicking through the magazine the ride organisers send out with the letter telling you that you haven’t secured a place in the ballot. The magazine contains page after page of ads from charities looking for people to ride for them and raise lots of sponsorship money. I came across an ad for Breast Cancer Now and, as I read it, I realised this isn’t just about me. It’s about the nearly 11,500 women and the several dozen men who die from terminal or secondary breast cancer in the UK every year and their families and friends. It’s about the women with secondary breast cancer from around the world that I’ve met on social media who are trying to change things so they get better treatments and care and who are advocating for more research to be done so that sometime in the not too distant future, secondary breast cancer will no longer be the killer disease it is today. And it’s about the scientists who are working to understand how and why breast cancer spreads, how it can be treated and what needs to be done in order to stop it becoming resistant to treatments.

Secondary breast cancer is when the cancer that began in the breast spreads to other areas of the body and forms a tumour or tumours there. It can develop years after you were successfully treated for primary breast cancer and it happens in an estimated 30% of cases. The vast majority of deaths from breast cancer in the UK are as a result of secondary breast cancer. Some people live with it for many years, but they’re a minority. Statistics are hard to come by but it seems that as many people die within two to three years of being diagnosed with secondary breast cancer as live beyond that.

Given the stage my cancer was at when I was diagnosed, I’m at high risk of developing secondary breast cancer. At the back of my mind as I was reading through the magazine and mulling things over was something somebody said some time or another, that if you really want to do something, do it today, because tomorrow you might wake up and find you can’t. So rather than wait and apply again next year for a ballot place, I went ahead and this very morning signed up to ride for Breast Cancer Now. I’ve paid my non-refundable forty quid registration fee and I’ve undertaken to raise a minimum of £650 in sponsorship money.

Breast Cancer Now is focusing on four areas: prevention, early detection and diagnosis, treatments and secondary breast cancer. It believes that by 2030, more than 50% of those diagnosed with secondary breast cancer will survive beyond five years. Its overall aim is that by 2050 no-one will die of breast cancer. That seems to me to be a worthwhile goal.

Cycling 100 miles in a day over the route in question won’t be easy. I’m nervous already. I love cycling. I love my bike. It really helped me during treatment. However, I’ve hardly been out on it since September last year, when I did a two-day bike ride with a friend to make up for my having had to cancel a long-distance bike ride to Brussels the previous September as by then I’d started chemotherapy. That same friend has a guaranteed place on the Prudential Ride this year, so hopefully we’ll do it together.

I've done one mass bike ride before and that was about 60 miles and about thirty years ago. I'm fit; I play lots of tennis and I run 5 or 10k two or three times a week but that’s not the same as long-distance cycling. I’m hopeless at hills (running and cycling) and there are, over the course, “leg-testing climbs”. I’d better start training soon.
