Paris Marathon 2027: split times, aid stations and how to run it
The next edition is on Sunday 11 April 2027 (provisional date: the organisers haven't confirmed it yet; in 2026 it was held on 12 April. Start time is indicative), starting in Paris (Champs-Élysées, France) at 8:30. Here you have the Paris Marathon route, split times for your target, what's at each aid station, how many gels to carry and the usual weather.
Paris Marathon: route and profile
Stations from the official website: from km 30.6 the source doesn't detail what's offered (the table only shows water). Confirm in the runner guide.
The course, section by section
| Section | Length | What it's like and how to run it |
|---|---|---|
| 1. Champs-Élysées → Bastille km 0 | 6 km | Downhill start along the Champs-Élysées, Concorde and the Rue de Rivoli, with thousands of runners. The downhill and the crowds launch you: the first 5 km, 5–10 s/km slower than your target pace. The marathon isn't won there, it's lost. |
| 2. Bastille → Bois de Vincennes km 6 | 15 km | East and a loop of the Bois de Vincennes, with gentle rises and fewer spectators. Settle into your pace and start your gels (the first around km 8–10). On the rises, same effort, not same pace. |
| 3. Bercy and the Seine embankments km 21 | 8 km | Back to the centre along the Seine embankments, with tunnels that dip and rise and the GPS all over the place. The tunnels break your rhythm: don't speed up on the way out. Go by the km signs, not your watch. |
| 4. Eiffel Tower → Bois de Boulogne km 29 | 6 km | You pass the Eiffel Tower and the Maison de la Radio heading west. This is where the real marathon starts: gel, water and focus on form (short stride, loose arms). |
| 5. Bois de Boulogne and finish on Avenue Foch km 35 | 7.2 km | The last 7 km through the Bois de Boulogne, with few spectators and the odd rise, finishing on Avenue Foch. The mental stretch: split it into 1 km chunks and find someone at your pace. Whatever you have left, from km 40. |
Route keys
- You aren't handed cups here: runners bring their own cup or soft flask, according to the event's website. Take a foldable one (it fits in a shorts pocket) and test it in training, because at the aid station you have to refill it while walking.
- There are stations with solids and liquids (water, bananas, dried fruit, savoury and sweet snacks) at km 4.8, 8.7, 13.3, 16.8, 21.3 and 24.2; water-only points (to refill your container) at km 22.5 and 29; and electrolytes at km 24.2. The source lists no gels: carry your own.
- You start on the Champs-Élysées and run through the Bois de Vincennes in the first half. The last 10 km are in the Bois de Boulogne, with big crowds at the exit and fewer spectators inside the woods: it's the mental stretch of the marathon.
- Paris has tunnels and walled-in streets along the Seine: your watch GPS drifts. Go by the signs at each kilometre, not by your watch pace.
2 more keys in WinWatts: with the forecast for the days before, the wind and heat, and your split times at your pace.
Split times
At an even pace (we haven't loaded the official track yet, so climbs and descents aren't adjusted: use it as a reference), with the clock time counted from the 08:30 gun. If you start from a later corral or wave, add the time it takes you to cross the start. Write yours down or wear them on a pace band: watch GPS usually reads long.
| Point | 3 h | 3 h 30 | 4 h | 4 h 30 |
|---|---|---|---|---|
| Average pace | 4:16 /km | 4:59 /km | 5:41 /km | 6:24 /km |

Aid stations: what's there and how much to drink
For a typical runner finishing in about 3 h 30: sip without stopping and take each gel just before an aid station, to wash it down with water.
| Where | What's there | Time (for 3 h 30) | You |
|---|---|---|---|
| km 4.8 | water, fruit | 8:54 | ~200 ml |
| km 8.7 | water, fruit | 9:13 | ~150 ml · gel just before |
| km 13.3 | water, fruit | 9:36 | ~200 ml · gel just before |
| km 16.8 | water, fruit | 9:54 | ~150 ml |
| km 21.3 | water, fruit | 10:16 | ~200 ml · gel just before |
| km 22.5 | water | 10:22 | ~100 ml |
| km 24.2 | water, sports drink, fruit | 10:30 | ~100 ml |
| km 29.0 | water | 10:54 | ~200 ml · gel just before |
| km 30.6 | water | 11:02 | ~100 ml |
| km 32.2 | water | 11:10 | ~100 ml |
| km 32.6 | water | 11:12 | ~100 ml |
| km 35.1 | water | 11:25 | ~100 ml · gel just before |
| km 37.0 | water | 11:34 | ~100 ml |
| km 38.8 | water | 11:43 | ~100 ml |
How many gels and how much to drink
What a typical runner (68 kg) needs depending on their time, with 35 g gels. When running the stomach tolerates less than on the bike: more than 60 g of carbs per hour only if you've trained it. Gels alone don't reach that figure (the first one comes around 45 minutes and none are due in the last half hour): the rest comes from drinking sports drink instead of water at a few aid stations.
| Time | Carbs per hour | Gels | Total drink | Sodium per hour |
|---|---|---|---|---|
| 3 h | 60 g/h | 4 × 35 g | 1.5 l | 300 mg/h |
| 3 h 30 | 60 g/h | 5 × 35 g | 1.8 l | 300 mg/h |
| 4 h | 60 g/h | 5 × 35 g | 2.0 l | 300 mg/h |
| 4 h 30 | 60 g/h | 6 × 35 g | 2.2 l | 300 mg/h |
Nothing new on race day: gels, breakfast, shoes and socks, all tested on your long runs. Vaseline on your feet, groin and armpits, and protect your nipples. If it's cold at the start, wait in your corral in old clothes you can throw away.
Paris Marathon: weather in early April
What the weather was like during the race (from the start to the finish of a 3:30 runner) in recent editions:
| Year | Low | High | Rain | Max wind |
|---|---|---|---|---|
| 2022 | -0 ºC | 9 ºC | 0.0 mm | 6 km/h |
| 2023 | 3 ºC | 13 ºC | 0.0 mm | 6 km/h |
| 2024 | 10 ºC | 14 ºC | 0.0 mm | 10 km/h |

| 2026 | 6 ºC | 11 ºC | 0.0 mm | 13 km/h |
When running, heat slows you down: allow roughly 2 % more time for every 5 ºC above 12 ºC.
