Various studies have shown that people continue to exercise longer when they listen to music because it distracts them from fatigue and pain. Energetic music is stimulating, whereas quiet music helps with relaxation and calming down.
The best music to run to differs for everyone. Do you use music for distraction? To get into your rhythm more easily? Some people prefer music with many beats per minute, others prefer quieter music and still others like to listen to a podcast rather than music.
On Spotify, you can find various running playlists sorted by beats per minute. This is a measure of the pace of the music and helps you to select songs that suit your running rhythm. To find the playlists, go to ‘Browse’, then to ‘Genres and moods’ and click on ‘Workout’. Scroll down the list to 'Running' and see the lists there.
