Double or Nothing: What a Two-Day London Marathon Means for the Likes of Us
Brace yourselves, Hart Road Runners. The London Marathon — that annual festival of chafing, questionable fancy dress and 1.4 million people refreshing the ballot results page — might be about to get even bigger.
Organisers have confirmed they are exploring plans to run the 2027 event across two days, on Saturday 24 and Sunday 25 April, with up to 100,000 runners taking part.
That would mean roughly 50,000 runners each day — nearly double the current field — and potentially a few more of us earning the right to limp proudly around south-east London.
So before the WhatsApp group starts arguing about whether this is brilliant or sacrilege — and it will probably be both — here is what it could mean for ordinary club runners like us.
The good news: your odds just got slightly less ridiculous
More than 1.1 million people entered the ballot for the 2026 London Marathon, and the application pool for 2027 was even bigger. With only around 15,000 to 20,000 places usually going to ballot entrants, your chance of getting a public place has been hovering somewhere around 1.5% to 2%.
To put that in running terms: you are statistically more likely to negative-split a marathon than to actually get into one.
Double the days, double the places — so the maths, in theory, tilts ever so slightly in our favour.
For everyone who has collected enough “Sorry” magazines from London Marathon over the years to wallpaper the spare room, that is genuinely cheering. More places could mean more first-timers, more charity runners, and more Hart Road Runners turning up to Tuesday sessions muttering about their 20-milers.
Club places: one spot, and we are agonisingly close to two
Here is the bit that matters specifically for a club like ours.
England Athletics-affiliated clubs receive club-guaranteed entries based on how many first-claim members they have — and the bands are stricter than many people assume.
For 2026, the tiers ran like this:
- Clubs with fewer than 10 first-claim members received no guaranteed entry.
- Clubs with 10 to 39 first-claim members went into a ballot for a place.
- Clubs with 40 to 189 first-claim members received one guaranteed entry.
- Clubs with 190 or more first-claim members received two guaranteed entries.
With around 180 first-claim members, Hart Road Runners sits squarely on one guaranteed place — tantalisingly close to the magic 190 that unlocks a second.
So, if you have ever wanted a reason to gently nag a running mate into sorting their first-claim membership, “you could be the member who doubles the club’s London allocation” is a pretty good one.
Whether a bigger, two-day field would shift any of those bands is anyone’s guess. The organisers are still very much in the talks and consultation phase, and the mayor’s office has not signed anything off. But for a club hovering right on the threshold, it is well worth watching. Even a small tweak to the rules could be the difference between one place and two.
The catch: Saturday or Sunday?
Now for the faff.
If you are in, you would not get to pick your day. You would be allocated either the Saturday or the Sunday.
That sounds trivial until you remember everything that orbits a marathon.
Your support crew would need to commit to a whole weekend in London, not knowing which day they are cheering. Long-suffering partners everywhere just felt a disturbance in the Force.
Travel and hotels for a Saturday race could mean an extra night away, and London hotel prices on marathon weekend already require a small mortgage.
The Monday after a marathon is brutal enough. A Saturday finish at least buys you a recovery day before work, which is one genuine win for the desk-bound among us.
And spare a thought for anyone hoping to run it with a clubmate or partner. There is every chance you could end up on different days, reduced to texting each other splits from your respective sofas.
The fast lot, and a quirk for the purists
For our speedier members eyeing Good for Age or Championship entry, there is an interesting wrinkle.
The Championship start traditionally sets off right behind the elite men. But under the two-day plan, the elite men’s and women’s races would reportedly be split across the two days — men one day, women the other — so where the Championship runners slot in is anyone’s guess.
If you are chasing a fast time off the back of the elite carnival, the logistics could look quite different.
That elite split is also where the purists start grumbling, and it is a fair point. Part of the magic of marathon day is that everything happens at once: the elites, the club runners, the charity runners, the fancy dress, the television coverage, the stories, the chaos and the emotion.
Split the elites across two days and you lose a bit of that single-day spectacle. Running media have been chewing this over for weeks, and the rough consensus seems to be: great for participation, perhaps a slight shame for the spectacle.
Growth versus tradition
The bigger debate comes down to growth versus tradition.
Nobody is arguing with the charity numbers. The event already raises an enormous amount of money, and a two-day version could raise even more.
But London already shuts down a big slice of Greenwich, Blackheath and the route for one day. Doing it across two days would test even the most marathon-loving local’s patience.
As ever, it is a balance between letting more people in and not breaking the thing that makes the event special.
The reassuring bit is that organisers are pitching this firmly as a one-off for 2027, partly to keep the race in London’s good books. So even if it is not for you, it may not become the new normal.
The HRR verdict
More places. Better odds. More of us on that start line. More money raised for charity.
But also twice the road closures, a coin-flip on your race day, and a slightly diluted elite spectacle.
On balance? We will take it.
Any plan that gives more Hart Road Runners a realistic shot at The Mall is alright by us.
No promises on which day you would get, though — so maybe keep the whole weekend free, just in case.
And start training your support crew’s patience early.
Got a strong opinion on the two-day plan? Bring it to the next club run — we’ll settle it over a post-session coffee.
