Spotify is adding a new suite of features for runners to its Fitness hub. Rolling out to Premium members on Spotify for iOS in the US starting today, Running Mode offers personalized playlists built around your workouts. Once you've clicked on the new Running Mode tab in the Fitness hub, you can choose between 25 presets that span different workout types and your preferred music genres, or opt for even more personalized results. When you press play, Spotify will create a playlist according to the parameters you've set, with "seamless transitions" between tracks to match your tempo. Spotify did once have a very similar tempo-tracking running mode in the app, but it retired it in 2018.
