It is more reasonable to measure each day in hours walked rather than miles. Most days, other than the summit day, will begin with breakfast around 6:30 AM and departure at 7 A.M. You will walk 4-5 hours with a break for lunch followed by another hour or two of hiking in the afternoon. These days are not long or difficult and you will be advised to walk slowly (“pole pole” in Swahili) by your guide.
