So, if Kaimes Hill is 9%, how do we work out our school run? how does the length to elevation thing work? (or does strava do it automatically for you?)

How do you work out gradient?

Strava has a cool route builder tool (Dashboard > My Routes) which can help you out with this if you don't already have a cycle along the route recorded.
Dragging the suggested Google Maps route to resemble what you actually do can also give a rough but less detailed idea of climbs involved.

I'm assuming the answer you want isn't:
[gradient]=sin^(-1)([change in height]/[distance travelled])
?

(That's only going to work if the slope is relatively consistent and could be approximated by the hypotenuse of a right-angled triangle. If not you'll have to work out horizontal distance travelled, and use inverse tan instead. Or the Strava thing.
Probably the Strava thing...)

Various websites will calculate elevation for you, and show you the gradient at any particular point. I normally use gb.mapometer.com
Average gradient (in percent) is just 100*(change in elevation/distance).

Thanks all - the 'strava thing' seems to work ;)
