The Paris Marathon is getting a full reset for its 50th edition. A new organizer, a new title sponsor, a new entry system, and a new name. If you've been planning to run Paris in 2027, here's everything you need to know before registrations open.
A New Organizer Takes the Wheel
After years under ASO (Amaury Sport Organisation, the group behind the Tour de France), the Paris Marathon is changing hands. Cadence Running United will take over as the official organizer starting with the 50th edition, scheduled for April 4, 2027.
Cadence Running United is positioning itself as a global major marathon operator, and Paris is its flagship acquisition. The transition represents the most significant structural shift the race has seen in decades. For runners, that means new systems, new processes, and in some areas, new standards.
The organizer change also brings a headline sponsor upgrade. ASICS becomes the title sponsor of the race, officially renaming it the ASICS Marathon de Paris. The partnership signals a serious investment by ASICS in the global road running scene at a moment when the brand has been pushing hard on elite performance, particularly following its association with major world marathon records.
The Lottery Is Coming. Here's What That Means for You
The biggest operational change for 2027 is the switch from first-come, first-served registration to a lottery-based entry system. Paris joins London, New York, Tokyo, and Chicago in requiring runners to apply for a spot rather than simply buying one.
This is a significant shift. For years, Paris stood out among major marathons precisely because you could secure a bib with speed and a credit card. That era is ending. If you're planning your 2027 race calendar, you'll need to factor in the possibility of not getting selected on the first draw.
Lottery systems bring both benefits and frustrations. On the positive side, they reduce server crashes, eliminate panic registration, and create a fairer distribution of spots across nationalities and experience levels. On the frustrating side, they introduce uncertainty into your planning, especially if you're building a full training block around the race. If you're mapping out a structured build toward a spring major, reading up on how to structure your training week during fall race season can help you stay sharp while you wait for lottery results.
Details on the lottery window, selection criteria, and notification timeline have not yet been officially published by Cadence Running United. Expect that information to drop in late 2026.
Entry Prices: What You'll Pay
Cadence Running United has confirmed the standard bib pricing for both races. Here's the breakdown:
- ASICS Marathon de Paris (April 4, 2027): approximately $185 per standard entry
- Half-Marathon (March 7, 2027): approximately $87 per standard entry
For context, the London Marathon charges around $280 for international runners, and the New York City Marathon sits north of $350 for non-members. At $185, Paris remains competitive on price for a World Athletics Label road race, which matters if you're working through a multi-major campaign on a realistic budget.
The half-marathon taking place on March 7, 2027 is a standalone event, not just a course element of the full race. At roughly $87, it's a strong value entry point for runners who want the Paris experience without committing to the full distance, or who want to preview the course conditions ahead of a future marathon attempt.
Reduced-Price Bibs: The Passerelle Option
One of the more interesting additions is the introduction of "passerelle" bibs, which translates roughly to "bridge" bibs. These are reduced-price entries made available to eligible runners, though Cadence Running United has not yet specified the exact eligibility criteria publicly.
In practice, this type of tiered pricing system is common in European road racing and increasingly relevant globally. It typically covers runners from lower-income backgrounds, local community organizations, or specific demographic categories the organizer wants to prioritize. Think of it as the marathon world's version of income-adjusted pricing.
If you believe you might qualify, watch the official registration portal closely when it opens. The passerelle allocation is likely to be limited, and eligible runners will probably need documentation to confirm their status.
The Course: Expect Stability, Not Reinvention
No official course map for 2027 has been published yet. However, Cadence Running United has indicated that the route is expected to remain essentially stable for at least four years under their management.
That's meaningful information for route-specific planning. The Paris Marathon course runs through some of the most iconic urban scenery in the world, passing by landmarks including the Arc de Triomphe, the Bois de Boulogne, and the Château de Vincennes. It's a relatively fast course with limited elevation change, which makes it appealing for runners chasing personal bests.
The four-year route commitment also suggests Cadence Running United wants to build consistency and familiarity around the race, which is smart from a brand-building perspective. Runners who train specifically for a course want to know it's not going to change dramatically year to year.
Elevation-focused training is less of a concern here than for trail or mountain races, but if you're also looking at other events on your 2027 calendar, understanding whether altitude training actually benefits road runners is worth your time as you build your annual plan.
How Paris 2027 Fits Into the Major Marathon Landscape
The Abbott World Marathon Majors currently includes Tokyo, Boston, London, Berlin, Chicago, and New York. Paris is not part of that series, but it holds a World Athletics Platinum Label and consistently attracts fields of 50,000-plus runners, making it one of the largest marathons on earth by participation.
The rebranding under ASICS and the shift to a lottery system are clearly moves toward elevating Paris into that upper tier of global prestige. Lottery entry in particular signals scarcity, and scarcity drives desire. Paris under Cadence Running United is betting that runners who apply and wait will feel more invested in the race when they get in.
For the record, the 50th edition on April 4, 2027 lands on a Sunday, which is standard for major European road races and works well for international travelers managing weekend logistics.
What You Should Do Right Now
Registration isn't open yet, but preparation can start immediately. A few practical steps worth taking now:
- Register on the official ASICS Marathon de Paris interest list when it goes live. Early notification is typically required for lottery participation.
- Start building your base if you're targeting a spring 2027 marathon. A 16-to-20-week training block puts your serious ramp-up beginning in late November or December 2026.
- Budget for travel and accommodations early. Paris hotel prices around a major marathon weekend move fast. Booking 12-plus months out is not overkill for a 50th anniversary edition.
- Have a backup race in mind. If the lottery doesn't go your way, you'll want a Plan B already scoped. Whether that's another spring European major or a different format entirely, having options reduces the stress of waiting. If you're open to other distances or formats, exploring the fall ultra circuit might give you a productive direction while you plan ahead.
If you're newer to marathon training and want to make sure your overall fitness foundation is solid before committing to a 26.2-mile build, benchmarking your current strength levels is a smart starting point. Assessing where you actually stand on key fitness markers gives you a realistic picture of how much prep work sits between you and a Paris finish line.
The Bottom Line
The ASICS Marathon de Paris 2027 is a genuinely new chapter for one of the world's most beloved road races. The organizer change, the lottery switch, the ASICS naming rights, and the tiered bib pricing all point in the same direction: Cadence Running United is trying to build Paris into a true global major, not just a large European race.
Whether that vision plays out will depend on execution. Lottery systems are only as good as their transparency, and runner trust takes years to build. For now, the 50th edition has the right ingredients to be something special. Mark April 4, 2027 in your calendar, and stay ready when that registration window opens.
