I’m just back from two months in Paris. Running in Paris is a challenge. The Bois de Boulogne has lots of dirt trails and is decently big, but to stay close enough to run there regularly too far from everything else I want to do. There are many other parks, but they are all small or smaller and involve a lot of loops to build a run of anything longer than 3k. We rode the Velibs (social bike system) up to the Buttes Chaumont (a fave park) one Sunday and ran 4 loops; along with a big crowd of runners and other weekenders. The Buttes is the only good place to find hills. Sure, you could run around the streets…
