How I Ran Sub-4 Hour in my First Marathon

My London Marathon Training header

This time last year I was in full panic mode at how on earth I was going to run 26.2 miles around London in a time I was proud of. I don’t just ‘try’ things. If I start something I’m getting it done properly. London Marathon 2019 was no different.

By the title of my blog it’s pretty obvious I’m not a runner, so it was my first marathon as well as never having actually done a running event before. From so much cycling you’d maybe think I’d find swapping my bike for running shoes a breeze, but I quickly found out it was a whole different type of fitness. A good 3-4 hours on my bike could match a 2 hour run effort-wise. It was a steep learning curve that’s for sure. That steep learning curve also means this isn’t a blog post for seasoned club runners, just those who jumped in the deep end like me feeling like a rabbit in headlights.

I owe a lot of my training inspiration to Rachel Ann Cullen, who is the author of ‘Running for my Life’. Her story was amazing to read as a lot of my previous reading was from athletes like the Brownlee Brothers. My head was full of speed sets when in reality I just needed to get miles in my legs. Rachel’s gone on to do London multiple times now, so she’s certainly moved to the seasoned runner category!

So how did I accomplish a sub-4 hour London Marathon simply?

From the start of October when the ‘Congratulations’ magazine dropped through the letterbox I only had 7 months to go from cyclist to runner. After reading Rachel’s book I streamlined my training plan drastically and here’s a little example of how it went.

So rather than having weeks broken down into a strict training plan, I had simple milestones to reach before the big day. For me it was a training plan that was realistic with a job where I’m on my feet all day. I had injuries along the way, but I think if I’d tackled London with any more training I would have had a DNF or even a DNS.

After running the Half Marathon in 1:51 I had a rough idea of what I could run London in, which was under 4 hours. From then on it was just a case of continuing to up the miles and try and stick to around 8 and a half minute miling.

For the 20 miler I clocked a time of 2:52.

Then smashed London in 3:57.

The point I’m trying to put across is that tackling London Marathon doesn’t need to be complicated. If you have a coach, then fab listen to them. If you still feel like a rabbit in headlights, then I have a few little rules to follow:

    Totally agree with you on the icy footpath tip. I skipped a week due to the snow for my first one and it made no difference. We need to remember that plans are a guide and we can be flexible.

    Great time by the way.
