As a police recruiter, one of my responsibilities is to train relatively sedentary people to run 1.5 miles at the 60% Cooper standard. Of course, this is stupid. This allows slower women (or older men) to graduate from the academy when significantly faster men (in their 20s) are booted out, but that's the plate I've been handed. Trust me, burglars don't turn around and adjust their running away pace based on the gender and age of the cop chasing them.
Typically, I'm given several recruits who have not been running at all, and I have 6-8 weeks to get them ready to run 1.5 miles for time. In the past, I've advocated working solely on their aerobic conditioning while trying to avoid shin splints, so I've had them do 2- to 3-mile runs on the dirt several days per week. Unfortunately, this is not getting the job done, especially for heavier folks. For example, my most recent challenge has been getting a 42-year-old recruit (6'02" and 220) down to about 9:00 pace, and despite regular 3-mile runs, he just can't seem to hold that pace for more than 1 mile.
Any suggestions, particularly from those with some exercise physiology knowledge?
