The route
A single loop starting on Boulevard Saint-Germain and threading the Bois de Vincennes and eastern arrondissements before finishing at Place de la Bastille. Largely flat with a lively city feel.
Entry fee
Indicative entry is £65 per runner. Confirm the current bib price on the official site; ballot, charity, and tour prices can differ. The weekend total (hotel, travel, extras) sits in the estimator, not in the bib price.
Where to stay
Le Marais and the Latin Quarter sit close to the start and finish; Bastille itself is ideal for the finish line.
Getting there
Charles de Gaulle is 35-50 minutes to central Paris by RER B; the Saint-Germain start is a short Metro ride.
That weekend
The expo village is at Grande Halle de la Villette; the weekend suits Seine cruises, the Louvre and a stroll along the Marais.
Sample 4-day trip
Arrive, explore, race, then head home. A proper weekend, not a rushed fly-by.

Day 2: Shakedown Run and Explore the City
Collect your bib at the expo at Grande Halle de la Villette . Allow time for queues at this massive half.
Jog an easy Seine-side shakeout. Afternoon for Louvre or Marais wandering . Early dinner near your hotel.

Day 3: Race Day
The loop finishes at Place de la Bastille. From Saint-Germain or the Marais, a short Metro hop covers most hotels. Arrive early.
Afterwards, celebrate with a long café lunch. Keep walking light: 40,000 runners mean crowded streets.

Day 4: Final Day
If the flight allows, one last Seine stroll or river cruise . RER B back to CDG is straightforward, but leave margin.
Three nights turns the world's biggest half into a proper Paris city break.
