Bloody hell...how much water were you carrying with you? Rob's 5.5L doesn't sound unreasonable, if a tad heavy.
I remember really noticing the dryness out there when I was mapping, probably going through twice as much water as I normally would when mapping around Perth.
Maybe he drank 1L on the spot and carried 4.5?
I had capacity for about 3L water plus an extra bottle of sports drink (event info suggested carrying 3-5L, but it's a very good thing the rogaine wasn't 30 degrees like Friday!). Could have left behind those 2 extra thermal tops, gloves & beanie though...
On the other hand, on their Sunday morning loop to the NW Andrew & Lachlan took it in turns carrying Eleanor in the backpack. Saturday afternoon they arranged a roster of Top End orienteers to look after her :)
I had to make my 2L + 2x 0.5L bottles last from 12:40pm to 10:00pm, and then again from 11pm to 9:50am. I just managed ok, but I had to be strict on my regular but short sips and I couldn't afford to waste any. Luckily it didn't get much hotter than about 21 degrees on Saturday afternoon, but it was still sunny and hard going in the big hills and spinifex.
@Jenny how did the heat compare to the Kamloops WRC
Ah, Kamloops 1998. Hotter than the Warrumbungles. Also, we saw a bear.
