Lovely course, some fantastic single track, not as well signed as the sdw but I'm sure centurion will take care of that with their customary efficiency.
Hills are sharper than the sdw too in my opinion
My mate down the pub says track running makes one leg shorter than the other and every few laps you should change direction to stop it happening. He also said that he read we're all supposed to run barefoot because some Indian guys invented it then taught some American dude who then invented barefoot shoes, but I don't really understand what that is because that doesn't make sense and I haven't read the book yet
BT if you're not going to sleep or you sleep on your back why not just go for a cheap yoga or foam mat? Cheap as chips weighs almost nothing?
As for the hokas it's personal choice, I can't imagine you walking the pennines in heels but the only person I saw in hokas this year literally binned them at the end of the race saying he'd never wear them again
Couple of things there bt, klimt mats are great if you habitually sleep on your back but if you're a side sleeper or a mover the holes aren't so great, your shoulder/hip tends to poke through the gaps onto the ground.
As for hokas I know they're a marmite shoe, personally I'm not a fan but if the weather is as it was this year then the extra height in the shoe may cause you ankle problems with so much extra lateral movement in the mud
