I like this definition ... but what is the minimum distance to ride before you would use them. For example my shortest ride is to drop my son at school - which is a mere half km (one way) and a drop of 15 m - and I don't notice it, and then where ever I go after that its probably up and down - but if you take where I was working a couple of weeks ago then it was 3 km away and a drop of 70 m (with a little sharp bump in the middle of that).
To the hill lovers on here that's probably nothing ... but I hate hills - especially that particular route back to my house! I'm never sure how much of it would be dismissed as hardly an effort. I would hate to live where some of you lived - or perhaps I would just have to get better quickly
. Luckily I would say that although it seems very up and down round here there aren't any what I would call long climbs.
