Yeah there are two routes drawn on the map, but Kristof's route isn't one of them. That said there may be other variants that were discussed but haven't been publicised. Or the course may have been changed for practical reasons and volunteers at CP4 may send everyone that way.
Kristoff's went this way '13 & '14

Theres talk on FB of alternate parcours for CP4 that was given out at the riders brief, I guess KA took one of these...
