Bootcamp-style roadwork: I run with a pack containing 35 lbs of weight. I know that in the military they carry packs with 45 lbs, and the total weight they carry is about 80 lbs. (weapons, etc)
Sounds crazy, but I've had great fitness results from training this way. It's pretty rigorous, the gradual addition of the weights cuts down on your overall distance until you get used to it. But boy what a workout. I have hills near me so it's even better. But no obstacle course. :(
My question: how can you accurately calculate calories burned under these conditions? MapMyRun doesn't have any capacity for this. . and I can't find anywhere else on the web that examines it either. Calories burned are always based on standard factors like the duration, speed, runner's body weight, etc.
I know the results are different because I can see my body changing week to week. Would be cool to know how many calories I am actually sweating out.
Thanks for any tips!

Having done that in Corps I would advise against running that way. It's way hard on your skeletal system than you know. I can see doing it every so often.
It's better to get your strain on by running uphill or just faster depending on your goals.
Nite Rider,
Here is my $0.02.
As dg12 pointed out, you may want to limit your pack runs due to injury risk. Basically the added weight is causing your body to work harder (increased intensity). You can also increase intensity more safely by simply running faster or uphill (unweighted). I like intervals on a track and hill repeats..
For when you do run / hike with a weighted pack:
I suggest you give serious consideration to getting some solid, arch supporting footbeds like Superfeet or the Sole heat moldable footbeds (Dean Karnazes or Ed Vistuers models). Consider it a necessity if 35lbs represents 15% or more of your body weight! They'll run about $35-$40, and make sure the person selling them to you knows how to explain what a good fit should be!!!!!1
Even if you have good biomechanics and arch structure,with the extra weight you are gonna put a lot of stretching force on the fascia than form your arches. Just ask any woman who has just given birth if she's gone up a half size in shoes..
Secondly, make sure you retire your shoes at every 300 miles. I can't stress that enough to runners, even if they don't run weighted.
Third, don't run weighted on asphalt, pavement, etc... Stick to trails, grass, dirt.. Or if you have access to a beach, ditch the pack and run barefoot in loose sand.
If you really want the long, drawn out anatomical reasoning, just respond, otherwise I'll spare you the details.
BTW 35lbs, are you going for Special Forces qualifications? Thats the standard pack weight used for PRT by both US and British military operator training.
'Retire your shoes every 300 miles' ? - sburger01, are you in the running shoe business by any chance?
My wallet starts to flap when I've done 500 miles or so on any particular pair, and the shoes in question never LOOK too worn at that point- but I'm told that this is about the maximum mileage you should expect; the cushioning qualities regardlesss of make or device will probably not function as intended by this stage- but 300 miles? are you sure? The Likes of Mr Mizuno etc. must love you!
On the weighted training subject I was going on a run and my son asked if he could join me. Of course I agreed and just planned on taking it easy. Well his rollerblades were REALLY slowing things to a walk so I asked him to grab my shirt and pulled him around a relativly hilly 5k course. He weighs 70 lbs to my 130. That was a pretty good workout and we had a good time working in tandem through the course.
The question is would this be a lower impact training method or would the hill repeats and intervals be a better idea?
After the effort I felt great but the next morning my hamstrings were plent tight.
p.s. Thanks for sharing your forum with me.

Rediscovering running
No one's mentioned whether or not they use weighted rucksacks or weighted vests. There's a difference in the way the weight is distributed over the body.
"If you want to add some resistance try doing body weight exerices say every mile say 20 press-ups or pull ups. Train smart dude. "
That's very different than running with weights. Press ups and pullups don't work any of the same muscles as running with a weighted pack does.
