First 18 miles are picturesque...and a fun run if you have trained for a steep down-hill. The last 8 miles, including the out-and-back, are absolutely miserable. The final 4-mile stretch down a busy road with anxious motorists on either side was really unpleasant. I ran next to a garbage truck for a stretch...stinky. Would encourage REVEL to look for other options over the last eight miles...especially the last four.
