For the record:
0:00:00 Bluff Knoll Rd / Chester Pass Road (06:00am)
0:36:59 Bluff Carpark
4:07:59 Fire Road
5:05:38 Bluff Knoll Rd / Chester Pass Road (11:05am)
Conditions were favourable with cloud only hanging over the higher peaks. Negligible bush-bashing & for the most part you could see your feet making running possible between Bluff & Ellen.
I took water from the tank at Bluff Carpark, the creek on the Fire Road between the Ellen & North Miripunda tracks & various dubious puddles en-route.
Verification photos via the Suunto app link. Pace/splits didn't seem to appear on the Suunto app public move, so I've added a link to TrainingPeaks where this is visible.
