re Graveyard
1) It's all on asphalt. Be prepared for a 100 miles of pounding on joints and back. Not the best race for minimist shoes, running sandels, barefott running etc
2) The wind plays a major factor. You will get no break from it the whole 100 miles. I recommend having/wearing a light/ultralight wind proof jacket. You will appreciate it particularly on the bridge crossing (about 2.5 miles around the 50 mile mark). Wind chill plays a factor when the sun is down.
3) The wind drives a lot of sand, especially at the start, just getting on to Hatteras Island (50-60 miles) and the last 10 or so miles before the finish. Sand gets into your shoes etc and the grit caused issues for me and the folks I ran with last year. I didn't wear gaiters last year but I will this year.
4) The course is point to point. Weather conditions may vary along the course. Aid station and volunteers are awesome but realize there are only four full up aid stations so you need to appropriately plan your nutritional needs. You wiil go 3-6 hours between aid stations. Water/heed stations are about 6 miles apart.
5) Last year aid station 3 was indoors (Rodanthe Community Center?). It was already dark and temperature was dropping rapidly by the time I got there but it povided a good place to transition to night clothing/gear.
