VAMCalculator Description

You might have heard a lot about VAM or vertical ascent in meters per hour to give it its full name. VAM is a measurement coined by Dr Michele Ferrari as a means of comparison between riders and climbs giving us an ability theorize and attempt calculate relative power output. It is important to understand that VAM is affected by the gradient. The greater the steepness, the greater the VAM at a given power output. The relationship between VAM and relative power output is expressed as follows: Relative power (Watts/kg) = VAM (meters/hour) / (Gradient factor x 100) This gradient factor ranges between 2.6 for a gradient of 6% and 3.1 for a gradient of 11% To work out the gradient factor take 2 + (% grade/10) This application will enable you to easily calculate your climbing VAM.
