Without taking any position on whether the horizontal distances in Glorantha are too short, I've got a few quibbles with you about the vertical distances.
My own map of west Sartar, uncanonical as it is, has Clearwine at about 2000 feet above sea level and the Upland Marsh at about 1250 feet above sea level - not the 3000-4500 foot elevation that you have it. For what it is worth, I think the Pharoah's Marsh is maybe some 500-750 feet above sea level.

Or in my case about 5 or 6 metres for every mile.

I think Furthest is maybe only about 1000 feet above sea level (maybe less), which gives it an average slope of 1 foot per mile.
