Getting caught by enemies or zombies will not cause you to "fail" a mission or episode and force you to restart. You can still keep running and complete it if you are caught. If you trigger a chase but don't feel able to/cannot speed up you do not have to.
Here's how chases work:
- When a chase is triggered, the app calculates your average pace over the previous 30 seconds
- By default you must increase your pace by 20% from this average*
- In order to escape you must either run at this increased pace for at least 100 seconds OR you need exceed that pace and pull much farther ahead from your chasers.
*Subscribers can alter the pace increase required to escape to anywhere between 10-30%
When you are caught, you'll hear the enemy or zombie noises get louder, an announcement they've been 'distracted' and that you have lost a number of supplies.
When you successfully escape, you will only hear audio that you have 'evaded' the enemies or zombies.
