Rode through over Feb 5 and 6. From Hanmer to Lake Tennyson is fine if a tad rougher than Molesworth. After that there are many slips, over which you need to ride in 4wd tracks. There were lots of bikes and 4wders on the road including a few 2 up on big bikes.
For me it was a handful with a fully loaded vstrom. I stuffed up the last water crossing and dumped the bike but i had a few somewhat out of control moments on the loose rocky downhills.
Quite a ride. Im very glad i was not doing it on my own.
