Paris is set to host the semi-marathon du Harmonie Mutuelle on Sunday, March 9, 2025, with record-breaking participation anticipated. Following the overwhelming success of the previous year, which boasted 48,000 runners, expectations are high for this year’s edition; with nearly 50,000 participants possible, this race is on its way to solidifying its place as one of the largest sporting events globally.
Starting from the iconic boulevard Saint-Germain, athletes will navigate through the stunning scenery of Paris, culminating at the celebrated place de la Bastille. The course will carry participants alongside the picturesque quais de Seine and through landmarks such as the Bibliothèque nationale de France and the château de Vincennes.
The semi-marathon is not just about the distance of 21.097 kilometers but also about participation. With 14% of runners hailing from abroad, the event embraces both local and international athletes. Many runners view this semi-marathon as part of their preparation for the Paris Marathon, which is scheduled for April 13, 2025, just weeks later.
Race day will see several staggered start times, ensuring smooth progress through the streets of Paris. The first wave of competitors, including elite runners, will kick off the event at 8:00 AM, followed by subsequent starting groups according to their anticipated finish times. Here’s a breakdown of the schedule:
- Elites and preferential group 1: 8:00 AM
- Preferential group 2: 8:01 AM
- Target time 1:30: 8:03 AM
- Target time 1:35: 8:12 AM

The swiftest finishers are projected to cross the finish line at around 9:00 AM, with the event officially peaking at lunchtime. Each year showcases the event as both competitive and community-focused; this year is no different with 46% of participants tackling this distance for the first time, and 13% of these aiming for brisk times of under 90 minutes, averaging speeds of 15 km/h.
"The semi-marathon of Paris has become, by its number of registrants, the largest worldwide," says ASO, affirming the race’s increasing popularity and status.
Participants are encouraged to embrace the challenge and enjoy the scenic course filled with supportive crowds, as they are cheered on by local residents and brass bands stationed along the route. The finish line experience on place de la Bastille promises to be the highlight, with thousands gathering to celebrate their accomplishments.
Over the years, the event has not only become popular with adult runners, particularly with women making up 44% of entries, reflective of growing inclusivity. This year marks notable progress from 35% women participants recorded in 2022. With such trends, predictions suggest the scales may tip toward more women participating than men by 2030.
Anticipation is mingling with trepidation as logistical preparations are underway. Street closures are already being enacted across multiple arrondissements, particularly from Saturday through to Monday, ensuring the safety and flow of participants and spectators. The conscientiously planned traffic restrictions make it clear: this is no ordinary Sunday.
It's also worth noting for those unable to make it to the race, the semi-marathon will be broadcast live. Viewers can catch all the action on France 3 Paris Île-de-France from 7:50 AM to 9:45 AM as runners take flight through the streets of Paris, capturing the spirit and excitement of the event.
With more than 48,000 participants, this semi-marathon once again highlights Paris's vibrant running culture. Runners of all abilities are encouraged to prepare, whether it's for competition or personal achievement, as expectations are high and motivation runs deep throughout the beautiful streets of the French capital.
