I have always liked fun trivia and details everyone else likes to skip over. One of those little items I like is marching cadence. It makes a hell of a difference when you run the numbers.
The US military uses a 30-inch step. Normal marching cadence is 120 steps per minute. That equals 3.4 miles per hour or a 17.64-minute mile.
Double Time is essentially a jog that uses a cadence of 180 steps per minute. That equals 5.1 miles per hour or a 11.76-minute mile.
Many readers will note that the Ranger/SF standard is 15 minutes per mile or 4 miles per hour. This is easily attained and maintained for long distances whereas double time is not.
A combination of Quick Time and Double Time can be used to attain overall speeds of 11-15 minutes per mile. This takes some practice. Start by adding 30-60 seconds of double time every 10-15 minutes of marching and gradually increase it over a period of many weeks.
Do not exceed 5-minute bursts of double time, especially with heavy loads. It is murder on the knees and hips. But it is a required skill for anyone in combat arms so practice it a bit so you know how to do it.
Never make running with a load a significant part of your PT program unless you want to retire early!
