Question: how many miles to lose 1 kg?
Answer: To go down in weight by 1kg, you need to accumulate a energy-deficit of something like 7000 kcals. Thus you need to run for approximately 7000/150 = 45 miles or 7000/90 = 74km. 10 km or 6.5 miles every day should just about do it. But this assumes that you keep your food-intake constant.
