Quo and route planning to Veliki Vrh (1,764 m – above Trnovo ob Soči)
For years we have admired Veliki Vrh from neighbor Štefka's garden in Trnovo ob Soči.
This year we set the task to conquer it.
Four guys, Branko, Drago, Matic and Dušan decided to use Quo program to find out if we are capable for the route at all and also tell the wives when to start roasting the pork.
The first step was manual drawing of the expected route into Quo program based on 1:25,000 map and calculation of required time for the feat.
For the calculation we had to predict our fitness factor. This is the time in minutes that a hiker (mountaineer, alpinist, "chamois",...) needs to climb 300 meters over a distance of 800 meters.
Not an easy task, as we had no idea what our factor was. So we estimated it at 25 minutes, because 15 minutes is already excellent fitness. Since we carried backpacks and assumed the terrain would be at least partly difficult, we added one difficulty level to Naismith's rule using Tranter correction and the calculation showed we would dig into the mountain for 4 hours and 23 minutes. By feel we took 4 liters of water per person and went. We recorded the route all the time with GPS. We were back in nine hours. We were at the top, and somewhere else.
The next day analysis followed. We transferred GPS data to Quo. To our great surprise we found that the recorded route matches the drawn route on the map very well. Of course we had to clean the track drawn by GPS of all noises caused by numerous trees on steep slopes and carrying the GPS logger in pants pocket. When we subtracted the delay due to searching for crossing over the torrent Globoščak, we calculated that we needed 5 hours and 36 minutes for the route to Veliki Vrh.
The route summary in Quo program revealed that we walked 7.2 km, ascended over 5.6 km distance, climbed 1,465 meters along the path and made 1,319 m elevation gain.
Backward analysis in Quo program followed, where we determined our fitness factor. It is 30 minutes and not 25 as we assumed. If our fitness factor was 40, we would need 6 hours and 30 minutes for the route. For fitness factor 50 minutes Quo program would determine that we are not fit enough for the route.
