Long trail runs are fine as long as there more than one rout choice; it has been a misconception in US course setting for years. Orienteers are to chose longer winding flatter trails vs straighter hillier trails, etc.
I have my mapping process finished, the problem is that mapped reentrant on a map was shown way two short, missing in at least one contour line. (see attached image)
Unfortunately, I left my maps at Sergei's house, can not compare with the original.
