the nice jumpy trail after the woodwork
That sounds like one of the more spurious Strava segments there! 🙂
I was there on Sunday afternoon, and as you exit out of the wood at Technicolour Berm onto the forest road (where you would normally turn left for 100m before climbing up to Black Bridge and then on to the jumps section or on to the newer woodwork bit), the diversion takes you right. You can then turn right after 100m back into the old red route, or continue downhill on the forest road a further 500m and pick up the newer red route.
