RE: Women runs 520 miles on treadmill in 7 days but doesn't get WR as Guinness says her witness doesn't count
In my experience, most treadmills in the UK default to displaying information in KM however there is usually an option on the screen to change the display to Miles (or at least there is one the ones at the two gyms I frequent).
Also, in her defence, I can't imagine she was running 75KM per day. With the rest and fuel breaks she would still be travelling at a pace of a easy walk and in the videos she was certainly jogging.
