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.
