You big softy. I used to run round the streets of Ho Chi Minh at 6:30 in the morning - just a swift 5K or so, but it was difficult to find a treadmill that worked properly in the hotels in the far east when I used to travel out there.
I can't speak for the treadmill accuracy. I would depend on you inputting your details though, so I would be tempted to suggest you use it as a guide.
