The London Marathon Effect: Why This Iconic Race Inspires So Many People to Start Running
- 2 days ago
- 7 min read
From its humble beginnings in 1981, when around 7,000 runners lined up for the inaugural London Marathon, to 2025 when a record-breaking 56,640 runners crossed the finish line, London has firmly established itself as one of the World Marathon Majors and one of the most famous road races in the world.
What Is the London Marathon?
The London Marathon is one of the six World Marathon Majors and one of the most popular road races in the world. First held in 1981, it now attracts more than 50,000 runners each year and millions of viewers worldwide. The race takes runners through central London past famous landmarks before finishing on The Mall.
Stick around until the end because I’ve got a little quiz for you about the first London Marathon.
Each year hundreds of thousands of hopeful runners enter the ballot, dreaming of receiving that golden email saying they’ve secured a place.
And each year… hundreds of thousands receive the other email.
You know the one.
But for the lucky runners who do get in, the real journey is just beginning.
Many runners who start their journey inspired by the London Marathon eventually aim to run their first marathon, follow a beginner marathon training plan, or find the best running app for beginners. We'll look at all that in the article
The Growth of the London Marathon
If you plotted the number of finishers over time (which I like to imagine doing on my old BBC Micro with a screeching dot-matrix printer), the graph would show a spectacular rise, especially since 2021.
The London Marathon now attracts global TV audiences in the hundreds of millions, proving one thing beyond doubt:
Running has gone completely mainstream.
Back in the 1970s, things looked very different. In his book Shoe Dog, Phil Knight, founder of Nike, wrote that if someone saw you running back then they might take a very wide berth.
Running without being chased simply wasn’t normal behaviour.
Fast forward to today and when I head out for a run I pass plenty of other runners doing exactly the same thing. Most races now even use wave starts just to manage the number of people taking part.
Running has come a long way.
How the London Marathon Inspires New Runners
Events like the London Marathon inspire thousands of people every year to start running.
And that has to be a good thing.
Interestingly, running shoe brands often report spikes in sales after major marathons. Apparently watching thousands of runners sweating, panting and collapsing dramatically at the finish line is incredibly motivating.
Who knew?
But starting running isn’t always straightforward. Done badly, it can lead to frustration or injury.
The key is to start slowly and build gradually, giving your body time to adapt to the new stresses you’re placing on it.
Here are my three best tips for anyone starting their running journey.
3 Essential Tips for New Runners
1. Start Slower Than You Think
One of the biggest mistakes new runners make is running too fast.
In the early days consistency matters much more than speed.
As you progress, you’ll discover that around 80% of your running should actually be at an easy pace anyway. That’s the secret many experienced runners follow.
A run-walk strategy works brilliantly for beginners while your body adapts.
And how often should you run?
Three times per week is usually the perfect starting point.
2. Buy the Right Running Shoes
This doesn’t mean the most expensive pair or the ones that make you look fastest on Instagram.
Running shoes are about how your foot interacts with the ground, and during a run that happens thousands of times.
If possible, visit a running shop where experienced staff can recommend the right shoe for your gait and running style.
Trust me, your future knees and calves will thank you.
And no, you do not need carbon-plated super shoes to start running.
Even I don’t own a pair.
3. Follow a Proper Training Plan
The biggest danger when starting running is doing too much too soon.
You’ll feel great one day, run too far, and the next morning wake up with an injury that sends you straight back to square one.
That’s why following a structured plan makes such a difference.
One app I often recommend to new runners is Runna.

Unlike a simple run-tracking app, Runna builds a personalised running programme tailored to your experience and goals.
It shows you:
What runs to do each week
How to approach each session
Pre-run tips
Post-run feedback
My favourite feature is the audio coaching. Put your headphones on and Runna talks you through your session, telling you when to slow down, speed up, walk or push a little harder.
It genuinely feels like having a coach in your ear.

The 6 Biggest Beginner Running Mistakes
If you’re new to running, try to avoid these common mistakes.
1. Running Too Fast
Easy running builds endurance and keeps injuries away.
Remember: there are no medals for the fastest injury.
2. Increasing Distance Too Quickly
Your bones, muscles and tendons all need time to adapt.
Push too hard and shin splints or Achilles problems will appear faster than the taxman on payday.
3. Skipping Warm-Ups
Personally, I stretch before every single run.
4. Wearing the Wrong Shoes
Again, getting proper advice from a running store is well worth it.
Your feet take a lot of punishment while running, treat them well.
5. Ignoring Strength Training
A few simple exercises at home can significantly reduce injuries.
Focus on exercises like:
Planks
Squats
Glute bridges
They strengthen the hips, glutes, calves and core.
6. Comparing Yourself to Others
It’s great to be inspired by other runners.
But comparison is dangerous.
Just because someone online claims they’re running their first 50-mile ultra after starting running last week doesn’t mean you should.
Run your own journey.
Many beginners make the same mistakes when they start running. I’ve covered the most common ones in my guide to the 10 biggest mistakes beginner runners make

Why Running Is One of the Most Rewarding Sports
The London Marathon has inspired countless people to take up running over the last four decades.

Related Running Questions New Runners Often Ask
How long does it take to train for a marathon?
Most beginner marathon training plans take 16–20 weeks. This gives your body enough time to gradually increase mileage, improve endurance and reduce the risk of injury. Many runners preparing for the London Marathon start their training about four months before race day.
How many miles should beginners run each week?
Beginner runners usually start with 10 - 15 miles per week, spread across three runs. The key is increasing distance slowly so the body can adapt to the stresses of running. But if you are just starting out then following a Couch 2 5K programme is a good place start, Runna has these programmes in the app.
Is running three times per week enough?
Yes. Running three times per week is often the perfect starting point for beginners. It allows your body time to recover between runs while still building endurance and fitness.
Do I need a running coach?
Not necessarily, but structured guidance can make a huge difference. Apps like Runna provide personalised training plans and audio coaching that replicate many benefits of having a running coach.
Why do so many people start running after watching the London Marathon?
Major races like the London Marathon inspire people because they show ordinary runners achieving extraordinary things. Watching thousands of people complete a marathon often motivates viewers to start their own running journey.
