Some route variants going on at the moment with 29 and 30 following the road and 11 and 96 taking a forest track rather than crossing Hawk Side - longer but I bet its more comfortable in the trees on a good track.
It happens every 3 years and its a fantastic route, great cake and loads of other food as well. Somewhere I have a route description but the memories include a punishing climb out of Lewes over a golf course, (don't be tempted to have pint in the real ale pub first) crossing Wiilingdon Hill towards East Dean walking towards the sea with the sun beginning to set - the section along the 7 Sisters to Cuckmere Haven was if anything even better- and care is needed crossing the railway at Southease in the dark. Just enter - you will get a route description in plenty of time if you want to recce - I just turned up on the day.
On the LDWA Hundred - and other walks/runs of 50 miles or more - nausea and vomiting is a common problem. Ken Falconer in his "Survivor's guide to 100s and other long walks" http://www.ldwa.org.uk/library/hundredsurvival/hundredsurvival.php recommends Bovril. Other suggestions are flat cola - a very common remedy, and milk. A different approach suggests that the nausea is a version of motion sickness - caused or worsened at night by the bobbing up and down of the light from a head torch. Personally I find that removing the head torch and holding it like a conventional torch is helpful!
What fantastic weather - well apart from the right handed sunburn. Great weekend. Achieved my (modest) ambition of not to be last quite comfortably - as a walker rather than a runner I was a bit bothered but need not have been. Really enjoyed the routes - apart from Weymouth front and a hold up on the bridge- loved the last day. Finished along the beach with the first runner pounding past me like poetry in motion - he was enjoying it too.
