If you look at http://www.compbio.dundee.ac.uk/~dmamartin/arthurs.png
there
is a route profile traced from the OS map. The profile is 1.21 km long and
rises from 38 to 121m.

So your power calculations are a bit off (too high by at least a fifth).

Hi David

I did look at the 1:50,000 Landranger but I couldn't make out the contours.
I ended up measuring it with my bike computer in miles and converting (not
ideal). I would prefer your version as it looks nicely detailed except it
does not resemble the ride. There is no dip at any point. And at the top it
(almost) levels out for about a third of the distance.

I suppose I could add a sort of cosmological constant to bring the power
output down to something realistic.

How did you create your cross-section?

Tom.
