What's changing for the 2027 edition
Like the Paris Marathon, the Paris Half Marathon changes organizer from 2027: the Cadence group takes over the race after years under ASO, and the half changes sponsor name to become the HOKA Semi de Paris.
Date confirmed on the race's official website (hokasemimarathondeparis.com) when this page was updated on October 27, 2026; the 2027 course is due to be revealed there in early 2027.
Date, distance and registration
The 2027 edition is set for Sunday, March 7, 2027, over the official half marathon distance (13.1 miles).
Bibs were allocated by ballot, with applications from September 8 to 30, 2026. The ballot is now closed; the official website announces an official resale platform from December 1, 2026.
How long you need to prepare
Running Workout's half marathon plan runs 10 weeks. For a March 7, 2027 race, that puts the start of preparation around late December 2026.
- 10 weeks of structured preparation, from base to taper.
- 3 or 4 sessions a week.
- A progressive long run up to about 18 km, finishing at half marathon pace.
The full plan details — phases, session types, long run — are on the dedicated half marathon plan page.
How to set up your preparation
Once you have your bib, just start the half marathon plan on the app's Plan screen, entering March 7, 2027 as your race date. Your AI coach then reviews these settings with you, and builds and pushes the sessions to your Garmin watch, week by week.
The plan stays editable at any time if the final course or the date were to change before then.
