They just updated the route with GPS tracks.
The 200 miles a day for two days is now 222 miles a day, second day has nearly 13000ft of ascent! So 444 miles 20,000ft ascent in 2 days :-(
Bit annoyed really because adding on 22 miles per day adds on at least an hour pedalling, probably 1.5 hours, it might just make the difference between people not achieving it.
Just in case anyone else here is doing it anyway!
