Ridden it a few times - your hands/wrists and backside take the biggest pounding so definitely double bar tape or gel inserts plus the plushest saddle and most comfy shorts (or two pairs!). Fit the fattest tyres you can, but ensure you've a couple of mm clearance or you'll grind to a halt - the dust is very fine and sticky and collects under the calipers. Minimum of 25mm tyres and run them at the lowest pressure you can ride without pinching - typically 5 bar. First few sector you'll think your bike is gonna break, but actually after a while you'll realise that you are the weakest link. Get some decent bottle cages like Tacx Tao not some lightweight bottle launcher. Drop your saddle down and back on the rails - slam it into the biggest gear you can turn and ride as hard as you can until you reach the end of the sector. Refuel loads at Raismes - before Arenberg - and keep both bottles topped-up in case you lose one.
