So I like to run. A lot. Last Friday I wanted to see what the treadmill display would do if I ran over 99:59 (99 minutes, 59 seconds). It autostarted a "cooldown" at 98:00 and kept counting up. After 99:59 it started back at 0:01 and counted up until 1:00, when it shut down.
Yes, that 10.9 number represents miles.
