The race started promptly at 8:15pm at the softball fields on Geng Road in Palo Alto - temperature was in the low 60's. I'd guesstimate there were approximately 500 runners in the 10k. The race is run under the full moon with very little additional lighting (trail map).
The course runs along a frontage road (hello 101!) and then onto the Bay. I've run this trail a million times, but very rarely in the dark. It is uneven and has potholes, so participants have to run with care.
Not coming close to a PR (I did take 6 months off after all), I finished at 58:37.
Overall, here's how I'd rate the run:
Organization - Well organized/staffed, clearly marked, even in the dark parts. Grade: A
Course - Scenic during daylight hours with plenty of wildlife. Night runs not quite as good, with the exception of the moon reflecting on the water. Grade: B
Aid-stations - Two aid stations, at Mile 1 and Mile 5. Mile 1 water straight out of a garden hose (blech!). Grade: B-
Swag: Traditional long-sleeve cotton shirt. I usually prefer dri-fit, but I wear this shirt around town like a badge of honor :-)
Looks like I was crushed by an 18 year old, with the winning time of 36:30
