In relation to 'training-paces calculator' and treadmills:
I currently do a lot of training on a treadmill. I'm used to the idea of having the gradient at 1% to compensate for wind-resistance, but is there a formula for compensating for speed ? I wan to do some intervals at speeds of 18kph, but the mill in the gym won't go faster than 16kph. Is there a way uf upping the gradient to have the same effect as upping the speed ?
