(In website) In case you wish to pursue absolute perfection, feedback about wha tseems a slight glitch:

eg route from Coldcotes to Simonburn (Northumberland). At about 3 miles, the profile is correctly showing a descent but it is highlighted as if an ascent. I have not seen this previously, so seems a rare thing, just drawing to your attention in case you are not aware of this happening.

Note by using the spot heights shown for each ascent from the trough to the peak, the sum of the 11 ascents (some v slight!) came to 466 ft which aligns exactly with the total ascent shown on the profile (470ft); so clearly the incorrectly highlighted descent is not corrupting your  overall data, which would have mattered slightly more.
