ZRX: Zombies Run! promo code

ZRX turns runs and walks into audio adventures. While you move, the story plays in your headphones — best known is Zombies, Run!, in which you are a runner collecting supplies for a town that survived the zombie apocalypse.

It works at any pace and anywhere: outdoors, on a treadmill, even in a wheelchair, and the story is mixed with your own music. Underneath the fiction is a proper fitness tracker with GPS, distance and pace statistics. Zombies, Run! alone has ten seasons of episodes, co-written by the novelist Naomi Alderman.
