Warning: This is a really novice question! I'm running the Country Music Half Marathon next weekend. I've read that the course is "hilly". I looked at the elevation map on RA, but have no idea how elevation changes relate to the incline % on my treadmill. I've run some "hills" on my treadmill (up to a 7% incline), but am wondering if that will have been enough preparation for next weekend. Anyone got any thoughts for this beginning runner? Thanks!

I've got a fever...
The incline or angle is the inverse tangent of the elevation change divided by the distance on the course. For example, if there is a 100 foot elevation increase over a 1 mile of the race course, the incline is calulated as follows: First, convert feet of elevation change to miles: 100 feet * 1 mile/5280 feet = 0.0189 miles. Second, divide the elevation change by the distance on the course: 0.0189 miles/1 mile = 0.0189 Third, take the inverse tangent of this number: incline = inverse tan 0.0189 = 1 degree
On your deathbed, you won't wish that you'd spent more time at the office. But you will wish that you'd spent more time running. Because if you had, you wouldn't be on your deathbed.
True. But if you want to think in terms of %incline instead of incline angle, no need to use the arctangent, just multiply your step 2 result by 100 to get %incline. %incline ≈ (elevation change)/(distance run)*100% For for the above example %incline = (100 ft)/(5280 ft)*100% = 1.89% same as above.
We are technically using a sine calculation (the distance run on the course is the hypotenuse), whereas %grade is defined as tangent-based. However, sine≈tangent for small angles.
Carol, working backwards from your 7% equates to about 370 feet in elevation gained per mile run. ( .07 * 5280 ft/mi = 369.8 ft ) Very tough indeed!
Hmm, I don't think Google maps consider the elevation (i.e., distance is the adjacent side of the triangle rather than the hypotenuse). Wasn't there a thread recently on that topic?

I'm running somewhere tomorrow. It's going to be beautiful. I can't wait.
Poor baby
wow...i think id rather chance the hills than have to do this math!
we dont have hills in my area so the treadmill has to do!

this thread had been dormant for nearly 3 years.
Am I doing this right?
Does this mean it qualifies as a Zombie thread? I'm not even sure zombie covers it...is there a level above that?
No excuses....
The undead? Zombies are technically not undead as they are reanimated corpses, but vampires? Well, they're undead

Oh it is definitely a zombie thread. Some zombies are just more powerful than others.
I should have come up with another name besides 'zombie thread' given the overpopularity of the zombie genre.
Ah well. Live and learn. And then die and come back to eat brains.
