It's accurate enough for the 50 km race. Elevation gain around 920 m.
For the 100 you have to know which bits of the profile to chop out...tricky enough even for a local. The airstrip ride down track S2 in the pines removes a few undulations that would have been encountered on track S1 (with coarse blue metal topping). The removal of the big loop down south from the pines and back up again takes away say 3 big climbs, and that depends on your definition of big I guess. For those who remember earlier editions, you won't be riding up the fenceline climb that's way down south after Trott Rd, not the long drag back up to Fingerpost Rd west of the smaller isolated pine planatation on Mulcahy Rd (incorrectly labelled as Dixon Rd on the map), and not the steep climb back to the pines up Burnt Mill East Rd from the Gisborne Creek valley.
Suffice to say it'll be shorter and flatter than the profile on the website...but still no cakewalk. Instead of over 2000 m elevation change, I'm guessing say 1800 m? You can do a post-event GPS data comparison on Sunday afternoon.
