Strava, one of the leading GPS-based run-tracking apps, has launched Strava Insights. The interactive running data tool aggregates nearly 5 million weekly Strava entries and breaks them into interesting data points concerning location, time and place, popular days for running and more.

The data refreshes each week and shows the most current 12 months of data from Strava members in its 12 most active cities.

Some of the data you can unearth includes:

— Paris runners are the fastest Strava users in the world, clocking workouts at an average pace of 8:56 per mile. New York is the fastest in the U.S. at 9:15 per mile.

— Sydney is the city with the most runners logging their workouts in the morning (between 5-8 a.m. local time) with 30 percent. Paris runners are more likely to run during the lunch hour, while Barcelona runners run at nighttime more than other cities.

— The most active day of the last 12 months in San Francisco? On May 17, more than 5,300 runs were recorded on Strava. The famous Bay to Breakers 12K took place that day.
