I am not a big fan of running but, when I do, I need music - preferably that matches my speed and rhythm. What Adidas Go promises is a soundtrack customized to your training by using the motion sensor in your phone to judge your pace and pulling music from Spotify.

The first thing you will notice starting up Adidas Go is that it wants a lot from you before it will show you any love. While it starts with a huge inviting "Start Running" message and a button in the center of the screen, you soon learn that it means "start going through all the stuff we need to sort out before we can let you go for a run".
In this process's defense, it is fairly simple but it does require you to look at their terms and conditions, sign in to your Spotify account, and grant a number of permissions, then allow it access to the motion, GPS, and notifications. After that you still either need to be constantly connected to a data connection or the program won't let you start (though premium Spotify account holders can limit the drain on their data by downloading playlists for offline use).
Right, nearly time to start your run. To ensure the music is to your liking, pick which playlists you want Adidas Go to pull songs from (either from your own collection or the app's) and off you go. Finally.
... before you can run.
Of course, nearly all of this is a one-time process and once you are on the move, things work far better. The music will change depending on your pace, often crossing mid track into something more in tempo with your gait. It isn't always instantaneous, and I get the feeling that the more music you have, the more accurate it will be, but it’s a fun way to stay motivated. Coming to a stop will find your session pause - handy if you are looking to judge your overall time while subtracting stops for things like traffic lights.
It would be nice to see some kind of "target pace" function to inspire better performance in the future, because in its current form the app simply settles for whatever rhythm you are setting.
Post run, Adidas Go tracks and saves your performance, including time, distance, and number of tracks. It keeps track of all of these in miCoach (a separate Adidas service) letting you easily look back at the intensity of previous sessions, all of which can be easily seen through the app's streamlined interface and design.
Bar the initial set up, I found Adidas Go a good accompaniment to the few runs I used it on. But, in truth, to get the most out of service you need an unlimited (or very generous) data plan on your phone - which I don't have.
For runners and joggers it is certainly worth a try, if only for the novelty.
