How to Conquer 26.2 Miles Without Losing Your Mind (Or Your Lunch)

It took me ten years to get a place in the London Marathon.
No, that’s not a typo. A decade of hitting ‘enter’ on the ballot website, all stemming from a silly bet I made with a friend back in college. Year after year, I’d get the polite “better luck next time” email. When my local running club, which I’d joined a couple of years prior, pulled my name out of a hat for their affiliated spot, I was over the moon. The dream was finally real.
I was also completely unprepared for the real challenges ahead.
My biggest mistake wasn’t during the months of long, dark, winter training runs. It wasn’t the injury that forced me to defer my place for a year. No, my biggest mistake was a rich, heavy meal the night before the race. Let’s just say I got a comprehensive, first-person tour of every single portaloo on the 26.2-mile course. All while trying to keep pace with a man dressed as Big Ben.
It was a tough lesson, but it taught me something crucial: most marathon guides prepare you for the race, but not for the reality. This guide is different. This is the real-world advice I wish I’d had. I want to show you that running a marathon is a huge challenge, but it’s an absolutely doable one. And trust me, it’s worth the effort. This guide will help you get to the finish line feeling strong, proud, and with your digestive system happily intact.
Part 1: The Golden Rule: Keep Calm & Run On
If you take one thing away from this guide, make it this: remain calm. Pre-race nerves are exhausting, and getting hot-headed on a run—pushing too hard on a day you feel good, or getting angry when it feels bad—always comes back to bite you. Always.
Your training should build you up slowly, not burn you out. Remember you are training for a marathon, not a sprint, there is no need to go over the top with intensity. Your training shouldn’t leave you on your knees. This also applies to your life outside of running. Stress has a way bigger impact on your physical state than people think. High stress levels can mess with your sleep, recovery, and even your motivation to get out the door. Think of “de-stressing” as a core part of your training plan, as important as any tempo run.
It’s a challenge that demands respect. And if you’re wondering what happens if you don’t train, this article spells out the painful reality.
Part 2: The “Flexible” Plan: Fitting 26.2 Miles Into Your Life
Forget what the purists say. You do not have to sacrifice your Sunday mornings at the altar of the Long Run. I did all of my long training runs on a Monday morning before work. Why? Because that’s what worked for me.
While I did my long runs on a Monday, finding your own right structure is key. Find out how to choose a plan that is right for you.
The perfect training plan is the one you can actually stick to. Be adaptable. Look at your week and figure out where the pieces fit. Can you squeeze in a run at lunch? Is a Tuesday evening better for your long run? Great. Do that. The key is consistency, not rigidity. This is your marathon, your training, and your life. Own it.
Part 3: Fueling for Success (And Avoiding a Tour de Portaloo)
Let’s talk about food. This is where so many aspiring marathoners go wrong.
First, let’s bust the biggest myth: the “pasta party.” A single, massive carb-heavy meal the night before your race is a recipe for disaster (see my portaloo story above). Carb-loading is a 24-hour affair. It’s about consciously increasing the percentage of carbohydrates in all your meals the day before the race, not stuffing yourself into a food coma hours before you need to run.
My second food lesson came from the kids that I coached. Over one Christmas period during my training, they bought me piles of sweets. I thought, “Great! An excuse to eat candy on my long runs!” It felt good at the moment, but I’d feel sluggish and recover poorly afterward. Now I know that reducing processed sugar speeds up your recovery and helps you see fitness improvements much faster. Save the treats for after – you can’t outrun a bad diet!
Finally, the salt story. On race day, I meticulously drank only water at every aid station. Smart, right? Wrong. I felt great until I crossed the finish line and my body staged a full-scale rebellion. I had flushed all the essential salts and electrolytes from my system. My first post-marathon “recovery meal”? A McDonald’s cheeseburger, consumed on the desperate hunt for salt. Don’t be like me. Make sure your hydration strategy includes electrolytes, not just water.

Part 4: Gear – Your Best Friends & The Over-hyped Money Pits
You’re going to be spending a lot of time pounding the pavement. Comfort is everything.
- Your Saints: These are non-negotiable. For guys, a good pair of anti-chafe running shorts. For the ladies, a rock-solid, high-impact sports bra. Don’t skimp on these. Your future, non-chafed self will thank you. However, your most crucial investment will be in a properly fitted pair of running shoes.
- Your Sinners: The most over-hyped piece of kit? Glucose monitors for people who don’t medically need them. Your body is an incredibly smart machine. If you fuel it with healthy snacks and balanced meals, it will level you out just fine. Save your money. Check out the Harvard research into this!
Part 5: Pro-Tips for the Start Line & The Mental Game
The final pieces of the puzzle are about winning the war in your head and mastering race-day logistics.
- Find Your Anthem: When it’s cold and dark and your motivation is low, you need a secret weapon. Mine was a playlist of the cheesiest 90s and 2000s dance music I could find. It was impossible to stay grumpy while listening to the Vengaboys. Find what gets you pumped—be it hardcore punk, a history podcast, or the sound of nature—and save it for when you need it most.
- The Start Line Hacks: Two crucial tips for race morning. First, wear something warm and disposable over your running kit. An old jumper or a bin bag will do. You’ll be standing in a crowded, cool pen for ages, and you don’t want to start the race frozen. Second, have a warm-up routine you can do in a tiny, cramped space. A few dynamic stretches and leg swings are all you need.
You’ve Got This. Now, What’s Your Question?
Running a marathon is a journey. There will be tough days, weird food cravings, and moments you question your sanity. But it is an absolutely doable challenge, and the feeling of crossing that finish line is worth every single step.
I’ve tried to answer the questions I wish I’d known. I’ve even answered the most common unspoken one: Yes, there are toilets along the route (always check your official race briefing!).
Now, it’s your turn. What’s the one ‘silly’ question about marathon training you’ve been wanting to ask? Drop it in the comments below. There are no bad questions here, and I promise to answer everything.
