If we are to believe the statistics, France has between 13 and 14 million regular runners. By this we mean those men and women who go out galloping at least twice a week. If we relate this number to the population aged 20 and over (32.3 million), we are close to 45% of adults who run regularly. France is therefore a country of runners. Just look at the number of participants in the Paris Marathon, which takes place this Sunday, April 2, to be convinced: 52,000 people are registered, it’s colossal.
