Sounds pretty much like the lower parts of the old race course mixed with the top sections of the new trail. Is the fireroad climb near the house the really steep one which passes there gate? I thought they weren't allowed to use the new trail for racing?
When I was up there last week Coillte had blocked the two top singletrack sections with logs. They had nearly finished with one section, then stopped and gone to the other leaving mayhem behind them. To be fair, they had used a log bridge over the trail to protect it from the machinery. Can't see them being finished for Sunday on previous form. The first week of felling they closed the top section of trail because they stopped work with one tree left over the trail on friday night. Sounds like a barrel of laughs for Sorrento to deal with.
Oh and 40 mins a lap is madness even for elites
