How Many People Are In The London Marathon

So, you want to know how many people are in the London Marathon? The short answer is: way too many to count on your fingers and toes. We’re talking about a massive, sweaty, determined river of humanity that takes over the streets of London every spring.

The official number for the 2023 race was around 48,000 finishers. That’s not even counting the thousands who sign up but don’t make it to the start line due to injury, a sudden fear of blistering, or a last-minute decision to eat three full English breakfasts.

The Sea of Hopefuls vs. The Actual Runners

Here’s the dirty little secret: the London Marathon doesn’t just let anyone waltz in with a pair of trainers. You either need a Good for Age time (meaning you’re basically a retired Olympic sprinter) or you get in via the infamous ballot. The ballot is like a lottery, but with less cash and more chafing.

Every year, over 400,000 people apply for a ballot place. That’s roughly the population of a medium-sized city all desperately hoping to run 26.2 miles. The odds of getting picked? Roughly one in twenty. So, if you’re reading this and you’ve never run a marathon, your chances of getting in are about the same as finding a quiet pint in Camden on a Saturday night.

But wait! The 48,000 finishers are only the tip of the iceberg. Charity runners make up a huge chunk. These are the lovely souls who raise thousands for causes like cancer research or saving the polar bears. And trust me, they are everywhere — usually dressed as a rhino or a giant teapot.

The Unofficial Crowd: The “Human Funnel”

Now, here’s where it gets weird. The official start isn’t one single “Go!” moment. No, no. The organizers split the runners into three massive waves: the Red, Blue, and Green starts. Why? Because if you let all 50,000 people bolt at once, the first mile would look like a zombie apocalypse with better sports bras.

It takes roughly 30 minutes just to cross the start line if you’re in the back. Imagine standing in a queue for a rollercoaster, but instead of a seat, you get a medal and a bottle of water. And the real party? That’s the 700,000 spectators lining the route. That’s more people than live in the entire city of Liverpool, all screaming “You’re almost there!” at someone who has just stumbled past mile 18.

Seriously, the crowd is insane. They’ll cheer for a guy dressed as a dragon, a woman pushing a pram, and a bloke who is clearly just walking for the last ten miles while crying. It’s like a giant, loving, slightly unhinged family reunion.

The Numbers Game: A Few Surprises

Let’s get a bit nerdier. The London Marathon is the largest annual fundraising event on the planet. In 2023, runners raised over £65 million for charity. That’s enough to buy a small island and a lifetime supply of energy gels.

Here’s a fun fact: the marathon’s average finishing time for men is about 4 hours and 30 minutes. For women, it’s around 5 hours. But that’s just averages. The actual bell curve is a beautiful mess. You’ve got elite Kenyans finishing in 2 hours and 5 minutes, while the rest of us are still on the route, high-fiving a man in a banana costume while trying not to vomit.

Also, about 1 in 20 runners will have to stop for a loo break. Yes, that’s roughly 2,400 people desperately searching for a portaloo while their legs scream ‘no’. And don’t get me started on the “runners’ trots” — let’s just say the Thames gets a lot of unusual “tributes” that day.

The Final Answer (Sort Of)

So, how many people are in the London Marathon? Officially, roughly 48,000 finish. But really, it’s hundreds of thousands if you count the 400,000 ballot applicants, the 700,000 spectators, the 5,000 volunteers handing out water, and the one poor soul who always has a panic attack at the start line. It’s a sprawling, chaotic, glorious mess that turns London into a single, sweaty, smiling organism for one Sunday a year.

If you ever get the chance to run it, do it. Just remember: the number of people is staggering, the pain is temporary, and the medal is heavy. Also, never trust a fart after mile 20. You’ve been warned.
