Well, it's free route choice... the most logical point to me appears to be where the little south-west ridge comes down from Knott Rigg... then get on the race path that was discussed a couple of pages ago.
Also worth noting that the Rigg Beck cp is not at the road, it looks to be exactly at the start of the climb up Causey Pike.
I also noticed that Whitelss Pike is shown as a cp on the map, but not listed on the details you get after you enter. Although seeing as you head directly over it, i suppose that's not really worth worrying about.
Race map is now on the Kong Running site.
