How did you work that out?
2013 17.9km Matt Speake 1.34.44
2014 17.0km Hector Haines 1.32.56
2015 15.4km Thierry G 1.26.29 (GG 1.30.29)
Seems pretty obvious that 2015 was slowest mins/km
I assume from awk's post that he is talking about height adjusted running speed. He is suggesting that even without the extra climb he would expect Bigland to be slower than Mynydd Llanxxx or Cold Ash.
The height adjusted running speeds (using 1000m added for each 100m climb) are
2015 3:50
2014 4:27
2013 4:18
I am inclined to agree with maprun - the 1:10 ratio of climb to distance is too generous.

I haven't looked through this in any depth, but I seem to recall figures of closer to 1:6.5 has been suggested as more suitable for elite men and 1:7.5 for elite women.
Using the 1:6.5 ratio gives adjusted min/km times of
2015 4:38
2014 4:45
2013 4:36
Considering that measuring climb on courses is not very exact, I don't think you can conclude that any of these areas is faster or slower than the others.
