Even when the horse has focused as best it can, its sight is only three-fifths that of a human. In other words, when looking at an object twenty feet away, the horse sees only as much detail as a person with twenty-twenty vision would if the object were thirty-five feet away.
If your horses don't get out and do this particularly often, then 20-30 miles (30-50 km) per day is probably a good estimate. Wikipedia supports this, with a claim of 30 miles (50km) per day for a small mounted company. This involves the horse walking for most of the duration of the day, with short breaks. Of course, a fit horse can travel further than this. Mounted soldiers would ride their horses 50-60 miles (80-100 km) in a day. This is more taxing on both the horses and the riders. Over the course of 6 weeks of travel, it's possible that good riding horses would get into better travel shape, and be able to go further, perhaps in the 40 mile (65 km) per day range.
