Today’s leg in Route to Christmas takes us to Italy and the Dolomites – to a relay called “Relay of the Dolomites”. The relay is a 5-person relay combining different age groups and men/women.
The leg is as usually first provided without routes – you may take a look at it and think about how you would attack this leg (if the image is too small, you may click on it to get it larger). This is mountain terrain where there is very good runnability in the white and quite good runnability in the light green. The darker green is slower, though, but you can get through short stretches. The 17th control is forked – we here ask you for the route from control 16 to variant B of control 17.
You find other maps from the area in omaps.worldofo.com here. See also latest additions in 3DRerun from this area in order to learn more about this terrain type.
Next you can draw your own route using the ‘Webroute’ below. Think through how you would attack this leg, and draw the route you would have made. Some comments about why you would choose a certain route are always nice for the other readers.
Then you can take a look at how the runners have solved this leg below. As this leg was forked, the analysis is not as straightforward as it would have been for an unforked control. However, from the GPS-analysis it looks probable that straight is faster when executed well. This is also in agreement with the course setters test running, which showed that straight was faster. Note that the women had the same leg on a different relay leg, and there none of the GPS-tracked teams chose to run straight – for women it might very well be that running around is faster (ref. earlier analysis which show that in the women’s class you can run further around than in the men’s class).
This first illustration shows the fastest runner running around versus the fastet running straight to the C-control. With 50 seconds left when coming to control C, is is quite probable that straight would be faster to B.
Looking at all runners running to control C, none chose to run around to the left – but several took routes halfway around to the left. Based on these routes, direct looks faster than halfways around.
See below for a density map of some of the ones who have drawn their routes so far.

Route to Christmas series
The Route to Christmas series at World of O is a pre-Christmas tradition at World of O – giving the readers the opportunity to do one Route Choice Challenge each day from December 1st until December 24th. If you have got any good legs in RouteGadget, GPSSeuranta or 3DRerun from 2017-competitions – or old forgotten ones which are still interesting – please email me the link at Jan@Kocbach.net, and I’ll include it in Route to Christmas if it looks good. Route to Christmas will not be interesting if YOU don’t contribute.
Not all legs are taken for the interesting routechoice alternatives – some are also taken because the map is interesting – or because it is not straightforward to see what to do on a certain leg. Any comments are welcome – especially if you ran the event chosen for todays leg!
