If you guys don't like these hard and crunchy mechanics of travel, we can change these rules.
While traveling, you can move at a normal, fast, or slow pace. A fast pace makes you less perceptive, while a slow pace makes it possible to sneak around and search an area more carefully.
Forced March. It's assumed that players travel for 8 hours in a day. You can push on beyond that limit at the risk of exhaustion. For each additional hour of travel, each character must make a Constitution saving throw at the end of the hour. The DC is 10 + 1 for each hour past 8 hours. On a failed saving throw, a character suffers on level of exhaustion.
Mounts and Vehicles. For short spans of time (up to an hour), many animals move much faster than humanoids. A mounted character can rode at a gallop for about an hour, covering twice the usual distance for a fast pace, but after that the mount will need to rest.
Characters in wagons, carriages, or other land vehicles choose a pase as normal. Characters in a waterborne vessel are bound to the speed of the vessel, and don't suffer penalties for a fast pace or gain benefits from a slow pace. Depending on the vessel and the size of the crew, ships might be able to travel for up to 24 hours per day.
Special mounts, such as a pegasus or a griffon, or special vehicles, like a broom of flying, allow you to travel more swiftly.
|Pace||Distance per Minute||Distance per Hour||Distance per Day||Effect|
|Fast||400 feet||4 miles||30 miles or 5 hexes||-5 penalty to Wisdom (Perception) scores|
|Normal||300 feet||3 miles||24 miles or 4 hexes|
|Slow||200 feet||2 miles||18 miles or 3 hexes||Able to use Stealth|
Travel speeds in the table above assume relatively simple terrain: roads, open plains, or clear dungeon corridors. But adventurers often face dense forests, deep swamps, rubble-filled ruins, steep mountains, and ice-covered ground--all considered difficult terrain.
You move at half speed in difficult terrain--moving 1 foot in difficult terrain costs 2 feet of speed--so you can cover only half the normal distance in a minute, an hour, or a day.
We're using a hex map for wilderness travel. A hex map is made out of tessellating hexagonal cells.
Our hexagons are 6 miles across on the short side and 7 miles across on the long side. The edges of the hexagons are 3.5 miles long.
The island that our adventure takes place should take roughly a week to get to any coastline from its center... and since most of it will be difficult terrain, the radius should be like, 18 hexes...
