Post How fast do I have to go? A guide to time and speed management while touring

Calculate average speeds with rest stops

How to use this table

I created this table to help you plan trips. Time and speed management is an important skill to master to make sure you get to your destination in the time alloted. This table will tell you what speed you have to go in order to average a certain mph. "What's the big deal," you ask. "If I'm going 600 miles and I drive 60 mph then I'll get there in 10 hours. Right?" Wrong! You forgot about stopping for rest/gas/etc.

If you want to average a certain mph, this chart will help you figure out how fast you will have to go based on how long you stop per hour. If you stop for 20 minutes every two hours, you'll use the 10 minute scale (since this is a per hour chart).

Example: Lets say you want to average 65 mph and you stop for 15 minutes every 2 hours. Look across the top for the speed you want to average (65). Follow the column down until you find the 7.5 min row (15 minutes every 2 hours is 7.5 min per hour). Where the column and row cross is how fast you'll have to go the whole time you're not stopped (72 mph).

Obviously, the longer you stop the faster you'll have to go to keep your average speed from falling.

I've now color coded the speeds. 65 mph and below is green, 75 and below is yellow, 85 and below is red and above 85 is purple. That way you'll always know what is still only 10 over.

Length of rest stop (in minutes) per hour
