Music is an essential element of a lengthy run, so adidas and Spotify have partnered up to release adidas go – an app that matches a runner’s favorite tunes with the pace of the workout.

Adidas go, which is only available for iOS, uses the iPhone’s accelerometer to measure a runner’s stride rate to match it with tracks from Spotify’s music library that have a similar tempo.

“Adidas go lets your energy level control the music that plays during your run, so you’re always in control,” Adrian Leek, general manager of adidas Running, said in a news release. “For the first time, instead of runners listening to music, music will listen to runners.”

The app streams tracks from Spotify that correspond with the interest of the user based on preferred artists and genres. Then, when the workout is finished, users can take note of  and save their workout stats – distance, time, pace, etc. – as well as any new music they discovered and enjoyed during their workout.

First-time users of the app will enter a seven-day trial for Spotify Premium, with the option of upgrading to Spotify Premium or using their local music library when the trial period ends.

Adidas go is currently available in the Apple App Store for the iPhone 4S and later models.
