Well, that depends on what "benefits" yer after.  First of all, getting out there and running 7 miles ROCKS no matter how ya slice it, Schromeister.  But as far as the high-intensity benefits, Here's what I found on various fitness sites:

MensFitness.com:

"Twenty minutes of high intensity interval cardio increases your aerobic capacity (VO2max) dramatically, maintains lean muscle mass, boosts your metabolism during and after exercise, and burns more fat calories than long periods of low intensity cardio.

Wait a minute! Sound too good to be true? It’s not. In one research study participants who engaged in 90 sessions of traditional cardio over a 20 week period lost 1% bodyfat, while participants who engaged in 25 sessions of moderate intensity cardio then 35 sessions of high intensity cardio over a 15 week period lost 3% bodyfat. Additional studies have shown that participants who engaged in short high intensity training lost 9 times more fat than those who performed long low intensity training. Longer low intensity cardio can actually be counterproductive for more fit individuals because it burns up hard earned muscle decreasing fat burning. 

And basically, for some people, it’s also incredibly boring and time consuming and doesn’t do much for your aerobic capacity.  Aerobic capacity?  There are a lot of folks out there who can run for miles and miles, literally hours at a time at low to moderate intensity but who nevertheless get seriously winded and can't keep up in, for example, a high-energy game of raquetball or full-court basketball"

BodyForLife.com:

"Emphasize quality over quantity when it comes to cardio. Your muscles need stimulation, but they also need rest. It’s better to do 20 to 40 minutes of focused, intense training a few days a week than put forth a LONGER, half-hearted effort every day.


BodyBuilding.com:

High intensity cardio is good for people who don't have hours a week for walking or jogging slowly on a treadmill or covering a lot of real estate outdoors.  The advantage of doing high intensity cardio is that you burn many more calories than low intensity cardio and you burn more fat in a shorter period of time."

Thanks for the info, Rob.  Very interesting......

Meister, I wonder what the author deems as a "half hearted effort". Should I ask him if an 8:00 pace is half hearted? :/O
I'll take my chances playing full court hoops against this clown, anytime, anyday.

D.A.L.U.I.:
The old rule was that jogging was the pace, less than 10/m, and you should be able to carry on a conversation w/ your jogging partner.  The "high intensity" stuff sounds like speed sprints in the old language.  Jogging plus speed sprints will bring off weight and increase cardiovascular conditioning.   But it's rough on the back and joints--that's what took me out of that game--two operations on a ruptured disk w/in 6 months in 2001.  I mention that just to remind everyone that everything, and I do mean everything, has a price.  Aristotle's Golden Mean, nothing in excess, is my motto now.
