Turn your workouts into zombie adventures
I haven’t tried this yet, because I, uh, left my running shoes in Norway, but Zombies, Run is certainly an amazing concept. It’s a running app for your phone that sets you in a story: 100 metres into your run you hear ZOMBIES CHASING YOU! You have to escape them, and pick up medicines and other supplies before returning home where you can log in and use your collected supplies. Apparently there’s a story being narrated as well, and the more missions (or runs/workouts) you complete the more the story develops.
I suppose Endomondo and Runkeeper slightly gamify your workouts, but this is taking it to a whole new level!
