Paris Marathon 2027 entries: registration should open soon

For years, the Paris Marathon followed the same script: run it on a spring Sunday in April, barely shake off the DOMS, and registration for the next edition would drop almost immediately. This time, though, it’s been a long, unusual wait. Months after the last race, still nothing: no date, no entry portal, no updates. For an event this big that typically sells out a year in advance, the silence has been weighing on runners. But there’s no real reason to panic. If anything, there’s good news: things are moving behind the scenes, and registration should open soon. Here’s what we know about the next Paris Marathon, an edition with a very particular flavor.

Why isn’t ASO organizing the marathon anymore?

Since 1998, Amaury Sport Organisation has been calling the shots at the Paris Marathon. Twenty-eight editions, a well-oiled machine, habits firmly set, and relationships built with every stakeholder. A continuity that felt almost guaranteed, much like the Tour de France, another property of the Amaury group.

But the story ended with the 2026 edition. The City of Paris, which owns the Paris Marathon and Paris Half Marathon trademarks, launched a new tender as early as 2025 to appoint the organizer for the 2027 to 2030 editions. The reasons? The event has become global, but it’s sometimes criticized for lacking local roots and for not going far enough on environmental commitment. The efforts ASO made recently on sustainability, like ditching plastic cups at aid stations, weren’t enough. In short, for some, the Paris Marathon has become more of a cash machine, with prices climbing year after year. So the City Hall decided it was time to reshuffle the deck. Three candidates entered the tender: ASO, the incumbent; an international consortium bringing together Playground and Oconnection; and a third name, then largely unknown to the wider public, the Cadence group, a partnership of three French players (Havas, Keneo and Avena Event).

And on May 20, 2026, the Paris Council made its call. Cadence won, with 78 votes in favor, 44 against and 13 abstentions. A chapter is closing, and for now the transition hasn’t been smooth. It’s been four months with no news at all about the event. Every communication channel has gone quiet: no social media, no website. So yes, that doesn’t mean the 2027 edition will be badly run. But for runners, this long silence reads like a somewhat chaotic handover.

Paris Marathon 2027 registration: why the wait, and when you should expect to grab a bib for a landmark edition.

Cadence is the event’s new organizer

On paper, the rules were straightforward. The sporting and operational project accounted for nearly half of the final score, ahead of the financial offer (around 30%) and environmental commitments.

One detail is worth highlighting: Cadence didn’t win on money. The group proposed a guaranteed annual fee of €3.5 million to the City, while ASO was around €4 million. On that metric alone, Cadence wasn’t the most lucrative partner.

What made the difference was everything else in the bid. Cadence came in with a strong social and environmental stance. A single low rate for people receiving RSA benefits. The removal of single-use plastics, already started under ASO but something Cadence says it will push further. And a desire to move beyond the postcard route (Eiffel Tower, Champs-Élysées) to pay tribute to Paris’s broader heritage. In other words, Paris wasn’t looking for a provider that could just write a big check and manage 60,000 bibs. The City chose a vision, greener and more social, for its two flagship running events.

What we know about registration

No, registration isn’t open yet. And no, there’s still no official date from the organizer. But what’s being whispered behind the scenes is at least a rough window: back-to-school 2026, most likely September. As for race day, the date being floated is Sunday, April 11, 2027, a familiar slot for this event and neatly placed in the running calendar, five weeks after the HOKA Paris Half Marathon. But nothing is set in stone: not the bib on-sale date, not the price, not even the platform that will handle entries.

This lack of precise information can leave some runners unsure about how to build their race calendar, but it isn’t really intentional. It’s mainly the direct result of a much bigger shake-up: the race has just changed organizer.

So what should we expect from the Paris Marathon 2027, in practical terms?

The distance won’t change, obviously: 42.195 km for the marathon and 21.097 km for the half marathon. Two races certified by World Athletics, with two prestigious labels: Gold for the Paris Marathon, and the standard label for the Paris Half Marathon. How those labels are renegotiated will be watched closely and will offer a first clue about what the next edition will look like. The higher the label, the more the race can attract world-class athletes.

The course. Nothing seems locked in yet. With Cadence, there’s been talk of a route that could change from one edition to the next to showcase more neighborhoods and Parisian architecture. But it’s still unclear whether that applies to the marathon, the half marathon, or both. Discussions with the police prefecture are still ongoing.

Registration. The time to platform, used under ASO, is a major partner of the former organizer. But it won’t necessarily be renewed automatically. Cadence could build its own tool or choose another provider.

Pricing. No numbers have leaked. The winning project mentions stronger accessibility measures, with dedicated rates for unemployed runners and RSA beneficiaries, for example.

The environment. This is one of the cornerstone points of the project. No more single-use cups and bottles. That shift was already in motion under ASO, and it didn’t win everyone over among participants. But the City of Paris seems to be making it a top priority. So it’s unlikely we’ll ever see aid stations with bottles or cups in Paris again. Cadence also wants to go further by offering runners plenty of options at checkout: race T-shirt as an add-on, clothing personalisation, optional medal, and so on.

The overall experience. This is another major change people are expecting. Where ASO leaned on logistics expertise and experience, Cadence is positioning itself with a more modern, energetic approach, with more brand activations: a new course, more on-course entertainment, and a redesigned digital experience that caters to spectators as much as runners.

ASICS replaces Schneider Electric and lands a prestigious naming deal

The first domino to fall after the organizer change, and a big one: every contract tied to the previous concession became void. Every single one. Everything has to be renegotiated, including ASICS’ deal with ASO, which had only just been renewed last year through 2031.

ASICS’ story with the Paris Marathon is worth telling, because it reveals what can happen behind the scenes of a naming contract. ASICS has been a Paris Marathon partner since 2009, but always in the second row behind Schneider Electric, the title partner since 2012. That position created real frustration for the Japanese brand: it couldn’t fully leverage the race’s potential to deliver an even deeper runner experience when the event carried someone else’s name.

With the Japanese brand on a roll in the running world for several years, the organizer switch was a golden opportunity. ASICS quickly made an offer to become title partner this time. The Paris Council approved the agreement on July 17, 2026. From 2027, the race will be called the ASICS Marathon de Paris, under a multi-year partnership whose exact duration hasn’t been disclosed. It’s a major win for ASICS and a clear statement of intent. Becoming title partner of France’s biggest marathon, it’s hard to imagine better visibility in the country...

For other brands and long-time partners, it’s also a reminder that nothing is guaranteed. Every contract linked to the former ASO concession is back on the table with the new organizer, and for now nobody knows exactly who else will be on board for 2027. According to a few corridor rumors, HOKA should remain the half marathon’s title partner.

This handover from ASO to Cadence gives the Paris Marathon a completely new angle. The race didn’t become one of the biggest marathons in the world by accident. It’s built on a precise balance between a route that threads past the capital’s most iconic landmarks and a profile fast enough to attract the best runners on the planet. Paris may not be a Major, but it’s still a hugely popular playground for elite athletes. And it’s also, above all, a massive street party: 58,853 runners on the start line in 2026, with one in two discovering the distance. Remove one of those pillars and you weaken the other. So Cadence has a serious job on its hands: modernize the experience and make the event greener without diluting a sporting reputation built over fifty years of history.
