Great run for me, good aid stations plenty of water and food, maybe a few of you should train harder and run quicker it is a race you know. Ran 3.22 only took 1-2 drinks at most stations there was plenty there going out and coming back. The route was very easy out and back.
Your be fine with your Cascadia's, I'll either wear old road shoes or a light trail shoe. The only shoes you don't want are fell shoes or with thick heavy soles.
I ran the NDW 50 in 8.54 (plus 2 miles extra going wrong at the end) ran Comrades in 8.02. It's hard to compare the two as you say trail v road. The NDW I had to walk most of the steep hills where Comrades I run most of the way with short walking breaks. The same with Eco Trail de Paris80k time 8.20. Comrades is more brutal on the feet and legs as your pounding up and down the road. Enjoyed both events if your've done the NDW you can easy do Comrades, it's just about managing the route thats way it's a good idea to go on the route tour they put on. I'll be back year to do my back to back.
Dave and Mel looked after me and gave me loads of advice for this year's Comrades, Dave's gets his green number in 2014. He will give you laods of help if asked.
