In my story, the hero and his comrades do alot of traveling both on foot and horseback. They live in a massive forest divided into two parts,in the darker northern part of the forest is where the sub-species of their race resides. The first part of their journey takes them across swamps to hills riddled with ancient caves. This part of the journey they are on horseback. I need to know how long it would take them to travel across the swamps to the hills, then how long for those they rescue from the cave-dwelling creatures to travel on foot back to their village in the forest. The hero must go on to the dark forest to seek answers concerning his quest then head north across the plains and finally to the mountains where his journey ends. At the same time, I have other members of his group in different places so I need to keep track of distance and time to make sure my chapters are paced correctly..how exactly do you do this and am I taking on too much for a beginner writer?
