Spotify and Adidas have teamed up to spur us on during those more difficult runs.
The sports giant and ELLE's favourite playlist providers have created the ultimate musical web-tool to keep runners motivated.
It prompts the user on their city, their favourite running track, their estimated running distance and how far they want to push themselves.
A few seconds later et voilà: a specially curated playlist, which features songs similar to your favourite running track - along with suggested popular running routes.
Boost your run here. (Don't mind if we do.)
