How to use the Timing Chart
First find the speed in MPH that you are supposed to travel across the top.
Then find the distance in miles along the left hand column. Where the two lines cross gives you
the number of minutes it will take to go that distance.
Example 1: To cover 5 miles of trail at 4 mph, it will take you 75 minutes,
or 1 hr and 15 min (1:15)
Example 2: To cover 3.6 miles at 4 mph, first look up 0.6 miles (9 minutes),
then 3 miles (45 minutes)
and add them together. At 4 mph, it will take you 54 minutes to cover 3.6 miles.
