I ran part of the cross-country course this morning and was there about 0800. By that time, the sun was above the trees and the field was bathed in sunlight. It was 73 degrees this morning and could be just a warm on the 30th. Be prepared for a summer run. Although there will be 3 waterstations for the 10K and one for the 5K, it might be a good idea to carry water.
I ran the 10K on Monday about mid-day. Good course but definitely hilly. It is mostly on mowed grass but it is cut long. Expect it to be wet on the day of the event. There are a few short stretches on pavement so spikes might not work well. I ran mid-day so the sun was high. On the day of the event there will be less full-sun but still some sunny stretches. There will be 3 water stations but it still might help to carry water.
I don't have a map that I can provide now but I'll look into getting one.
The 1/2 marathon course overlaps with the RMR course but it is not the same.
