Course description for Sunday from the NPS website:
The riders leave the grass field, over a wall and descend quickly to run just above the forest road giving good access for filming as they travel along the trail at speed for over 750m.
A man made track climbs in steps back upto the village field, giving good opportunities for passing.
After the grass field they follow a short swoopy section of the famous Dalby Red route down to the forest road.
The riders climb again before a fast descent on man made track with different route options for the optimum line down towards Worry Gill.
The riders descend into Worry Gill, a fast rocky and slippery descent down a narrow steep sided valley surrounded by tall pines, all totally natural and untouched. All watched by spectators from the vantage point at the top of the Gill.
They race along the valley bottom and hop up on to the level bench along the trail side.
They riders then hairpin back onto the very steep technical climb up a bermed bends followed by a steep narrow technical descent with tight hairpins and rooty drop offs.
They then have a flat run out with a tech area, in front of large spectator viewing point.
The riders then climb steadily up for 70m in just 550m on an ancient sunken track, giving good overtaking opportunities.
They reach the summit of the climb on natural trails winding through in pine woods, before descending down natural trails to the forest road.
The riders drop in and out of Worry Gill again, in front of the large spectator area at thehead of the Gill.
They climb steadily adjacent to the forest road giving ideal spectator and TV access.
They now cross the Forest Drive in to The Pace Bike Park at Dixon’s Hollow. This is a purpose made bike skills course which gives a great viewing opportunity for spectators to see the riders up close on a tight swoopy course incorporating a cork screw bridge mini table tops and jumps. Then back across the Forest Drive to the start/finish straight.
Getting towards the end of the lap the riders join the existing forest trail through mature Beech Woodland.
I expect you're right Will, there will be alternatives in place for the bits we're using, but there will be less space for parking etc as well.
