In its natural state, your brain is inclined to sync your footsteps to anything with a repetitive beat… train tracks, the person stomping loudly next to you, and of course music. Try it! While listening to a song, try and slow down or speed up the pace. When you start, you’ll think “that’s easy,” but when you don’t realise it, you’ll notice that you’re back at the pace of the song.
This subliminal synchronisation is the bit that can help you maintain a base pace and help you achieve a PB. So playing the right songs, at the right pace, through your headphones during a run can help you run more efficiently.
