Why do people run marathons?
People run marathons because the distance is big enough to feel like a genuine adventure but achievable for ordinary runners who prepare for it. The pull is a mix of challenge, the months of training with friends or a club, the rare thrill of running through a city closed to traffic with crowds cheering, and a finish line that stays with you for years.

Ask a non-runner and the marathon sounds like a strange hobby: get up very early, run a very long way, then walk down stairs backwards for two days. Ask someone who has done one, and you usually get a long pause and a slightly faraway look. Something about the distance gets under people's skin.
A distance with a story
The marathon has a legend attached, which helps. The name comes from the story of a Greek messenger running from the battlefield of Marathon to Athens, though historians debate how much of that tale is true. The distance itself was fixed later: the standard 42.195 kilometres was set in 1921, based on the course used at the 1908 London Olympics.
So when you run one, you are running a distance that has been agreed on for a century, raced by Olympians and ordinary people on the same roads. That shared history is part of the appeal.
The challenge is just the right size
A marathon sits in a sweet spot. It is long enough that nobody can fake it on the day; you have to prepare. But it is not so long that it is only for the extraordinary. Plenty of people who were never sporty at school finish one by building up steadily over months.
That combination, hard but possible, is irresistible to a lot of people. It is a goal you can say out loud in one word, and everyone understands it.
The months before matter as much as the day
Ask finishers what they remember and many mention the training as much as the race. Long Sunday runs with a club. Early mornings when the city is still asleep. Discovering the riverside path you never knew existed. A long run that ends in a café is one of life's simpler pleasures. If you want company for that, our guide to finding a running club is a good start.
Training also gives shape to a season. It turns "I should run more" into a plan with a date at the end.
The city closes for you
Big city marathons do something remarkable: they shut the roads. Bridges, avenues and squares that are normally full of traffic belong to runners for a morning. Bands play on corners. Strangers hold out orange slices and hand-drawn signs. Someone shouts your name off your bib and suddenly you can run another kilometre.
There are few other times as an adult when a crowd will cheer you for simply keeping going. It is quietly moving, even for the most cynical runner.
The finish line
Then there is the last stretch. Whatever your time, crossing that line after months of work is a feeling most people struggle to describe without getting a bit emotional. The medal goes in a drawer; the memory does not.
Reasons that are perfectly good
People also run marathons:
- to mark a birthday, a new decade or a fresh start;
- to raise money for a cause they care about;
- because a friend talked them into it over dinner;
- to see a new city on foot, from the middle of the road;
- because they wanted to know if they could.
All of these count. Speed is optional.
Reasons to wait
A marathon is a big commitment of time and energy, and it is not a requirement for being a real runner. If a half marathon or a 10K feels like more fun, that is a perfectly complete running life. Our guide on whether you're ready for a half marathon is a gentler step up.
FAQ
Do you have to run the whole marathon?
No. Many finishers walk parts of it, especially water stations and hills. Check each race's time limit, which tells you how long the course stays open.
What is the hardest part of a marathon?
For many people it is the later kilometres, when the novelty has worn off and the finish still feels far away. Starting slower than you think you should is the advice you will hear again and again from people who have been there.
Is a marathon only for fast runners?
Not at all. Big city races are full of people running, jogging and walking at all sorts of speeds. The cheering is just as loud for the back of the field.
How do you pick your first marathon?
Look for a course you would enjoy seeing, a time limit that suits you, and a date that gives you plenty of months to prepare without rushing.
