Travel Pace

A group of characters can travel overland at a Normal, Fast, or Slow pace, as described in Playing the Game. During any journey stage, the predominant terrain determines the characters' maximum travel pace, as shown in the Maximum Pace column of the Travel Terrain table below. Certain factors can affect a group's travel pace.
Good Roads. The presence of a good road increases the group's maximum pace by one step (from Slow to Normal or from Normal to Fast).
Slower Travelers. The group must move at a Slow pace if any group member's Speed is reduced to half or less of normal.
Extended Travel. Characters can push themselves to travel for more than 8 hours per day, at the risk of tiring. At the end of each additional hour of travel beyond 8 hours, each character must succeed on a saving throw or gain 1 Exhaustion level. The DC is 10 plus 1 for each hour past 8 hours.
Special Movement. If a party can travel at a high Speed for an extended time, as with a spell such as Wind Walk or a magic item such as a Carpet of Flying, translate the party's Speed into travel rates using these rules:
Miles per hour = Speed ÷ 10
Miles per day (Normal pace) = Miles per hour
× number of hours traveled (typically 8)
Fast pace = Miles per day × 1⅓ (round down)
Slow pace = Miles per day × 2/3 (round down)
If the characters are flying or their special movement allows them to ignore Difficult, they can move at a Fast pace regardless of the terrain.
Vehicles. Characters traveling in a vehicle use the vehicle's speed in miles per hour (as shown in Equipment) to determine their rate of travel, and they don't choose a travel pace.
