Just a quick one (hopefully), the hillscore on a route, what exactly does it relate to?

Now I know that the higher the number, the hillier the route but how is the number produced? Is it something to do with amount of ascent over distance or steepness of ascents or number of ascents or ascents vs descents....??

It's not important really but I feel like I need to know :)

I think it is ascent plus descent, in metres.

I do hope not, that would be boring and a bit pointless...

It can't be, the route I've just added has 60 up and 58 down but a hillscore of 116???

You're right! 60 + 58 = 116 could perhaps be a rounding error, but a route of mine here has 371m up, 340m down for hillscore of 724 - not 711.

Maybe uphill counts more to score than down, or maybe it's just a sampling error thing, no idea! Some uphill only or downhill only routes could be informative .. as could Lord Fetch ;)

Bump to see if anyone has an answer.

Ive just been looking at a route with about 530m ascent and descent and a hillscore over 1000, yet another route has about 400m ascent and descent and a hillscore of about 330, so it can't just be related to the ascent/descent figures.

Actually, now I look more closely at my saved routes, almost all the hillscores are roughly the ascent and descent numbers added together. The one I mentioned above seems to be some weird anomaly.

I've just added two routes - the second one the same as the first, but in reverse.

Route 1: ascent 63m, descent 17m, hillscore 123.
Route 2: ascent 17m, descent 63m, hillscore 33.

The hillscore is (roughly) twice the ascent for both (which would make it look like ascent + descent for most routes, since most routes are a loop with ascent and descent the same).

That makes sense, but I wonder why I have an odd one where the hillscore is less than the ascent? This is a loop where the start and end point are the same.

That's a good question Fragile - I've looked at some others and they all appear to be just under twice the ascent - I can't think what would make that one route of yours so different.
