Despite the COVID-19 pandemic keeping people away from gyms and group fitness classes, running shows no signs of slowing down. According to Strava's 2020 Year in Sport report, 55 percent of runners on the exercise-tracking app hit a new personal record (PR) in their 5K, 10K, half-marathon and marathon distances in 2020.

And it seems like most runners are taking to the sidewalks and streets to rack up their miles. Even with some gym restrictions lifted, only a third of gym members actually returned, according to a November 2020 survey from RunRepeat. In fact, since the pandemic started, 59.1 percent of active adults say that exercising outdoors, such as running, is one of the best ways they're staying fit in 2021, per the brand's 2021 Fitness Trends report.

Here are some essential running stats you should know to keep you motivated and safe next time you're pounding the pavement.
