I walked the trail last month to scout the trail because the trail network in the park is confusing through many parts of the trail. It's a nice area but all the trails are blazed the same color (yellow) and the route is along trolley track for a short section). I decided to take a run at the record this morning because it was such a beautiful day. Had a few small navigation hiccups that cost a little time but nothing major. I ran alone, didn't have any support (other than my gps to keep me on track) and I didn't need any water during the run.
