London Marathon – Everything You Need to Know
If you’re thinking about tackling the London Marathon, you’ve come to the right place. This guide breaks down the big questions: how to sign up, what to train, and what to expect on race day. No fluff, just practical advice you can use right now.
How to Register and Secure Your Spot
The first step is getting a bib. The official lottery opens in the spring, and slots fill up fast. Make sure you have a valid email, a UK address (or a charity partner), and a credit card ready. If you miss the lottery, look for charity spots – many charities reserve entries for fund‑raisers. Those spots often come with a fundraising target, but they’re a reliable backup if the lottery doesn’t work out.
Pro tip: keep an eye on the official London Marathon website for the exact lottery dates. Set a reminder on your phone so you don’t miss the window. A quick click at the right moment can be the difference between running in April and watching from the sidelines.
Training Basics That Actually Work
Most runners aim for a 16‑week plan, but the key is consistency, not perfection. Start with three runs a week: a long run on the weekend, a steady mid‑week run, and a short, easy run. Increase the long run by about 10% each week, and drop back every fourth week to let your body recover.
Don’t ignore strength work. Two 20‑minute sessions of core and leg exercises each week reduce injury risk and improve running efficiency. Think planks, lunges, and single‑leg bridges – simple moves you can do at home.
Fuel matters, too. Practice your race‑day nutrition during long runs. Experiment with gels, sports drinks, or real food like bananas to see what sits well in your stomach. The goal is to avoid surprises on race day.
Finally, schedule a few cut‑back weeks where you run less. Those recovery periods are when your body actually gets stronger.
Race Day Essentials
On the morning of the marathon, arrive early. The start line opens three hours before the gun, and you’ll need time for bag drop, bathroom, and a quick warm‑up. Wear the shoes and clothing you trained in – race day is not the time to try brand‑new gear.
Bring a small pack with a water bottle, a quick‑energy snack, and a rain jacket if the forecast looks grim. The London route is fast, but the weather can be unpredictable, so be prepared.
During the race, focus on pacing. The first 10 km should feel comfortable; you can speed up gradually after the halfway point. Use the crowd energy – the cheering crowds along the Thames and the finish line in The Mall can give you a huge boost.
After you cross the finish line, keep moving for a few minutes to prevent blood pooling. Hydrate, stretch lightly, and celebrate – you’ve earned it.
Whether you’re a first‑time marathoner or a seasoned runner, the London Marathon is a unique experience. Follow these steps, stay consistent in training, and you’ll enjoy one of the world’s most iconic races.
