The London Marathon 2026 is set for Sunday 26 April 2026. If you’re running (or even just thinking about it), this is the point where it starts to feel real.
By now, most people have done the bulk of their training. What matters is how you prepare in the final stretch, not just physically, but practically.
The last couple of weeks: don’t overdo it
It’s tempting to squeeze in one last long run or “prove” you’re ready. Most experienced runners will tell you not to.
This is the taper phase. You’re not building fitness anymore, you’re protecting it.
- Ease back on mileage
- Keep runs shorter and lighter
- Prioritise sleep (it matters more than one extra run)
- Stay consistent, not intense
Turning up slightly undertrained is better than turning up injured.
You’re not running it alone. Thousands of others are right there with you, step by step.
Race week basics people forget
It’s usually the simple things that trip people up.
What’s worth sorting early:
- Your race number and registration details
- Travel plans (London gets busy)
- Where you’ll meet people after the race
- What you’re wearing — and actually testing it beforehand
Nothing new on race day. Not shoes, not socks, not breakfast.
Know your limits on the day
The atmosphere of the London Marathon is unreal. Crowds, music, adrenaline — it can pull you into running faster than planned.
That’s where people burn out early.
- Start slower than you think you should
- Stick to your pace
- Walk if you need to, it’s normal
- Listen to your body, not just your watch
Finishing strong feels better than starting fast.
Hydration starts before race day. Don’t wait until you’re thirsty to think about it.
Fuel, hydration, and nerves
You don’t need to suddenly change your diet. Stick with what’s worked during training.
- Eat normally in the days leading up
- Stay hydrated, but don’t overdo it
- Have a simple, familiar breakfast on the day
And nerves? Completely normal. Even experienced runners feel it.
Watch out for common issues
Long-distance running puts stress on the body, even if you’ve trained well.
Things to keep an eye on:
- Dehydration
- Muscle cramps
- Blisters or foot pain
- Dizziness or overheating
If something doesn’t feel right, don’t ignore it. There’s medical support throughout the course for a reason.
Training gets you to the start line, but consistency and patience get you to the finish.
After the finish line
Crossing the line is a big moment, but what you do after matters too.
- Keep moving for a bit (don’t just stop suddenly)
- Rehydrate and eat something light
- Stretch later, not immediately
- Expect soreness for a few days
And yes, stairs will feel personal.
Final thought
The London Marathon isn’t just about time or pace. For most people, it’s about finishing something they committed to months ago. If you’ve trained, shown up, and made it to the start line, you’ve already done the hard part.
Take it steady, enjoy the atmosphere, and get yourself to that finish line!
