For about 10 years I tracked all my races with Casio-type hand-held split times, and counted climb on each leg: I found that if I increased the leg distance by around 7-10 x the climb counted by contour crossings, the effective leg speed was more or less constant. Other factors ended up being more important, like the maximum height difference for a single climb, climb on a good path vs white forest (paths matter a lot more uphill than downhill).

Thanks a lot, Bernt, Nixon and Rob! My dream scenario for “Route to Christmas” was always that I would prepare the basis and illustrations for a good analysis, and that the community would contribute in analyzing the leg like you have done for this particular leg. Unfortunately there are few high quality comments like yours; more of this would really have increased both the quality and fun of the calendar! More of this :-)

If I remember correctly there is a report in Scientific Journal of Orienteering tha found that for men 10 m of climb was the equivalent of 80 m extra running (for women the ratio was closer to 10 to 100). Rob´s data show 10 m climb to 82 m extra distance.
In other words the route choiceds are equal.

Approx climb:

Kral 200m Mudrak 135m

distance run:

Kral 2083m Mudrak 2616m

so 533m extra distance for 65m less climb

S shaped routes (like Kral’s) are often a bit longer than they look – ie compared to Mudrak’s route you don’t save as much distance as you think.
