Formula to Calculate Return Time

The estimated return time is equal to the sum of:

  • meet time
  • 15 min
  • 2 times the drive time oneway
  • the time spent hiking
  • the time for all breaks (pit stops, lunch, etc.)


  • The meet time is 8:15 AM.
  • The time hiking equals the hike distance divided by 2 mi/hr.
  • The time for all breaks is 2 hr.

You’ll need to adjust for earlier or later meet times, a different hiking speed, and/or shorter breaks.
