My point was more – who decides when a trail is DH ? As Northwind points out, some of the easier trails at Inners are marked on the map as DH. The fact that it isn’t a measurable criteria is what I don’t like. You can’t have rules around safety issues, which require significant preparation from both organiser and racer, based on subjective criteria.
It is all just a bit silly. If it was that simple I would go around the course the day before the inspection and put up a pile of signs that say “XC TRACK HERE”. Its a foolproof scheme…
