Never done the 24 hours at K (only done one 24 hr race so far), but I do ride K quite a bit. If I remember correctly, the course is fairly dry, mostly single track, climb up and descend down. Not terribly rocky, watch for slippery roots. I don't believe there are any snowmaking pipe crossings.
If I remember correctly, most of the course is to the looker's left of the Snowshed area?
