A new nighttime quarter/half/full marathon in Indy

Just found this new event last night.
The 1st Annual Planet Adventure Winter Quarter/Half/Full Marathon at Eagle Creek Park in Indy.

All three start at 6 PM on January 28, 2012.
It is a 6.55 mile loop with nearly all on single track trail.
The race cutoff time will be 2:00 AM.

I am thinking about doing the half - maybe the full for some experience at night with a headlamp and handheld to get ready for pacing at the Umstead 100 in late March.
It might be a little cold then or not.

Charles, I saw that and it looked interesting. We have a local race about that same time every year, so it may end up being a conflict for me.
