I hate running on a treadmill, however the question for you more experienced runners is: does say an 8% grade on treadmill equall an 8% grade on a road? Why? Who Cares? You ask? Well getting ready for Great Wall Marathon in may and while I run out side all the time my running buddies are stuck indoors in PA all winter and must use treadmill. Thanks Dan

Very different. I do almost all my training on my treadmill so I have gotten pretty used to it. It mainly depends on your treadmill. Some treads will go slightly slower when the incline is increased, totally screwing with you pace and giving you false stats. Most of the newer treads dont though. The main factor is wind resistance. I usually add 2 or three just to make up for the wind, since on a tread there is obviously no resistance. And be careful about holding on when you run, I used to and it made an irregularity in my step and actually started messing with my legs. So if you wanted an 8, I would probably put it at about 10.5

Thanks for the info. I'll pass that along to my snow bound buddies up in PA. A side note about treadmills for those of you that can run on the infernal contraptions ( I have a mental block about'em ).... My buddies wife was running on hers last year and did not wear the "deadmans switch".. she fainted while running and the tread wore away a bunch of skin on her side where she fell on to the thing!!! Scary!!! Thanks Again Dan

Ah man that's not cool I really hate wearing the stupid clip all the time, but with how fast it goes and having almost been thrown off, I don't want to take any chances...

After starting the treadmill you hold the 'Incline Up' button down until it reaches '8'. For outside, describing grade is a little like describing green so I can only help you determine the grade of a hill you might be considering. I believe to get the grade of a hill you divide the change in elevation (the vertical distance) by the horizontal distance. The trick is getting the vertical and horizontal distances. Vertical can be estimated either by getting the elevation approximations of the bottom and top of the hill from Google Earth. You could consult a topographical map as well, but that's so yesterday. You could measure the length of the hill in Google Earth as well, but I'm not sure how it handles elevation. If you measure the hill length manually with, for instance, an odometer or measuring wheel, or assume that Google Earth takes elevation into account when calculating distance measures, then you don't exactly have the horizontal length, but for a quarter mile its probably close enough. --IGNORE NEXT PARAGRAPH IF YOU'RE OK WITH THE VERTICAL MEASURMENT ABOVE. GEEK MOMENT-- If you want to be more exact you could take the square root of the difference of the distance squared and the vetical distance squared (Excel formula: SQRT(D5^2-F5^2)) for your closer approximation of the horizontal distance. --GEEK MOMENT ENDED-- If that makes your eyes glaze over you can just approximate based on hills you know. For instance, I believe the trail up the front of Kennesaw Mountain averages about 11%. That includes the relatively level mid section so the first quarter mile may be steeper. I have a little trough going out of my neigborhood that includes a half mile hill and a quarter mile hill that are both about 8% by my above calculations. Based on the greater difficulty in managing the smaller hill, I can attest to some hills can be more 8%er than others. Your last option is to find a steep hill that's at least a quarter mile in length and just start running. Hope I helped rather than hurt with all that!
