For the future chase sequences in my campaign decided to combine all the movement effects into tables that fit into a single page. I find it easier to look info from table instead of calculating it with the rules.
It contains now a table for movement rates between 1 and 14, effect of athletics on the speed when walking, running or sprinting. It also has a table for the common modifiers for movement like encumbrance, armor and fatigue. It has also the effects on ranged combat.
Here are the tables as PDF.
I also added similar tables for swimming.
