Hello! This is my first post so, banzai me!

Anyway, I'm currently working on a ES D&D campaign which will take place mainly on Vvardenfell (unless something goes awfully wrong..). I'm planning to make the map ridiculously large compensating this vastness with the towering insectoids. But how fast should they be? With back of the envelope calculations considering a leg swap at 2 meters (or 6 feet) and about 5 leg swaps per 3 seconds (after looking at 6-legged animations on google) the minimum speed goes up to about 95 km or 58 miles per day. But this can easily go up considering that insects should probably tire slower than mammals so the cycle would be about 10 hour instead of 8. Does this speed make sense to you?

P.S. On a different matter: considering that silt striders could also be used as carriages this should have a big impact on economy (larger, quicker carriages)..
