Why World Cancer Research Fund?

Hi friends, 

On 26th of April 2026 I'll be running the London Marathon. It's not the first one (it'll be my 3rd) but it's a special one: it's THE London Marathon, it's close to home, and it's the first time I run it for a charity. I'll also train hard for this, as I have a time goal that's ambitious for me: run a sub-4 hour marathon. So I'd love it if you could help me support the World Cancer Research Fund!

Why the WCRF? Like most of us, people very close to me have had to deal with cancer, and go through the ordeal of learning the terrifying news, go through often several waves of treatment, hoping for remission. I'll be running with a special thought for my father in law who passed away from a brain tumor 5 years ago. And my American host family's mom, who went away with breast cancer almost 30 years ago. 

But cancer is not ineluctable. It can be  detected earlier, prevented, and more and more, cured. Research is what is making incredible progress in these different areas possible, and we need to keep pushing forward.

Every day around 1,100 people will hear the words ‘you have cancer’ only in the UK. Over 420 of these cases could have been prevented, that’s a staggering 155,000 people every year. World Cancer Research Fund, are passionate about reducing this number.

As part of an international network of charities, they’ve been funding life-saving research, influencing global health policy and informing the public since 1982.

While society continues to search for a cure, their prevention and survival work helps people to live longer, healthier, and happier lives – free from the devastating effects of cancer. The money I'm raising plays a huge part in keeping this going.

What a day!

Thursday 30th Apr
What a day it was! Of course, it was a historic day with the largest number of finishers ever (>59,000), the first time any runner has ever run a marathon in a race under two hours (and they were two!), three runners under the previous world record on the men's side and one on the women's side... Of course, that we only learned after we ran our race. For me, running a large marathon in one of the six majors for the first time, I could not have anticipated the level of support, the atmosphere, and the intensity of emotions along the whole 42K. Mind-blowing. The kind of experience that keeps playing as a film in your head in the next days after. It wasn't the race I wanted to race in terms of time. It was hot for me, and then I didn't manage that well. My heart rate was much too high from the start, a sign that I was consuming too much energy. So predictably, I hit the infamous wall, and I had to deal with very heavy legs and low energy in the last 10k. But lots of lessons learned. You can only control the controllables. And so I'm hoping that this will help me do next time even better than my objective was today. Thank you so much for your support and your contribution to WCRF. 

Just a few more days to go!!

Friday 17th Apr
Work is mostly done, over 1,000k run, and some hiking and backcountry skiing on top + S&C etc. A few massage appointments, osteopaths, a couple of pairs of shoes replaced... Last stretch is about taper, ie. reducing volume to get to the day with fresh legs, and maintain the base fitness built over the past few months. Then last 2-3 days will be all about carb load -- eat loads of carbs, make sure that muscles store as much glycogen as possible to use over the course of the race (croissants, pizza, pasta, yeay!). Excited to get there...

wow wow Arc of Attrition done

Thursday 5th Feb
What a tough, and what a beautiful race!
Arc of Attrition is a trail race, with distances ranging from 25k to 100 miles, and as if follows the Cornish coastal path, lots of elevation from beach to cliff and repeat. 
I've been dreaming to race it, and as it fell 2 months before London it felt like a good target to already start building good fitness. Some fitness I needed!! I was racing the marathon distance, but with 1100m+ it was going to be spicy... (London, and typical flat marathons have less than 100m of elevation). I did underestimate how much harder the legs would work, going up and down already early in the race. By 10k I felt I had already run 20k. Hard it was, and adding also a very muddy terrain, where your legs are constantly adjusting to avoid slipping, my pace went down and down and down as the time passed. I finished in just under 6.5 hours, ecstatic to get to the end and finish... But it was beautiful, amazing sunny views and scenery (we were luckier than some other races that started earlier and had rain and wind to add to the hardships), and incredible support.
After a couple of days of painful legs, a week of recovery with a couple of walks and a small run, I'm back on the London training plan. Onward!

Properly launching the fundraising today... an update

Thursday 15th Jan
Sooo... I'm getting into the thick of training for London now. After a feel-good HM personal best in September, I've kept training at moderate levels, ran an amazing HM trail in November in the English South Downs (hilly but lovely views and great vibes). And since the beginning of December started training for the Arc of Attrition -- a UTMB trail in Cornwall, along the coastal path. I'll do the marathon distance, which with 1,000m+ of elevation feels quite a challenge. I won't run all of it though, I see this as part of the London training and don't want to compromise the following training weeks. But finishing it will definitely tick the box for me, it('s also my first UTMB50. Hoping for not too much mud or wind... So for that I've needed to increase the volume in weekly km and in long runs, and recently reached 30k long runs, including the last one with full trail gear (backpack of close to 4kg).  I'll take a quick breather after that before getting into the build blocks for London and get to the heaviest weeks of training. Glad that I've dodged any injury so far, but need to keep disciplined about S&C, that's the only way to avoid it... Will post again after the Arc (on 25/1). Thank you for following!!

Getting to London - training and races

Wednesday 24th Sep
I'll try and post some updates here regularly, but as I'm starting on this journey I want to give you a peak into what the next few training months will look like. Most people start marathon training 3-4 months before the race, but as I'm setting ambitious goals for myself I'm building from 9 months before...

To get to London in the best shape possible:
- from July 25 to Oct 25, I will be working on building strength, and increase my ability to run at a faster pace on (slightly) shorter distances. To measure progress, on 5 Oct I'll race a half-marathon (21.1k), aiming to run it in less than 2 hours (it would be a first!). Likely a number of parkruns also to try and bank PBs...
- starting in Nov 25, I'll start working on my fitness base for long distances, and doing work on hills and trails, which will lead to a fantastic ultra trail at the end of January: the Arc of Attrition UTMB50 -- that's a 40k trail with 1,000m of positive elevation in Cornwall along the coast. It will be amazing with good weather, but may be quite tough with bad weather...
- then starting in Feb 26, I'll build on that trail training to top it off with marathon training all the way to end of April...

I am very excited!!
