Time to hit the treadmill after my Body Pump express class, for a bit of speed work. So I turned the Zombies, Run! app into accelerometer tracking mode and enabled zombie chases. I set the treadmill to a nice and steady 6mph, planning to up it to 8mph for the chases, but it didn’t look like they were going to kick in (possibly because this was a special mission), so I upped it to 8mph and then a chase was enabled forcing me to run at 9mph for a minute to avoid getting caught. No further zombie chases after that but what was supposed to be a 30 minute mission ended up being a 45 minute one.
