Paris Marathon Pace Calculator & Race Plan
Paris starts on the Champs-Elysees and runs east through the city before looping through the Bois de Vincennes and returning via the Bois de Boulogne. The course has more elevation than people expect, with about 212 meters of gain including some real hills in the two parks.
The Bois de Boulogne hills in the last 10K are where the race gets honest. If you've been running too fast on the flat sections along the Seine, those late hills will find you. April weather in Paris ranges from cool and rainy to surprisingly warm.
