**How to Calculate an Elevation Gain for a Treadmill**

Whenever we travel for work or when the weather goes against our training schedule, the trusty treadmill can be a real life saver to get the workout done. Here’s how you can get the elevation training in using a treadmill!

**Step 1**

Note the percent grade, or incline, setting of your treadmill. For example, 6 percent.

**Step 2**

Divide the percent grade by 100. For example, 6 / 100 = 0.06.

**Step 3**

Calculate the horizontal distance you have run on the treadmill. For example, you have run 2.5 kilometers. 2500m x cos [arctan (0.06)] = 2500m x cos [ 3.43º ] = 2500m x 0.998 = 2495m.

**Step 4**

Multiply your answer by 0.06. For example, 2495m x 0.06 = 149.7m. You have completed an elevation gain of approximately 150 meters (rounded up).

**Using Arctangent**

**Work Out Slope Distance**

Divide your target elevation gain by the percent grade and divide by the cosine of the arctangent of the slope ratio. For example, 150m / 0.06 = 2500m / 0.998 = 2505m.

**Work Out Percent Grade**

Divide your target elevation gain by the horizontal distance. For example, 150m / (2500m x 0.998)= 0.06 x 100 = 6.
