Cool, good luck! With a seven hour cutoff you will be sure to get a medal and shirt. Wikipedia says January is the "Cool Dry" season, which sounds good, but gives low temperatures of 22.6°C (72.7°F) and highs of 30.3°C (86.5°F).
Maybe that explains the crazy starting time?
Gun Start: 3:00 AM
Cut off: 10AM (7 hrs)
I'm going to try to beat the Oprah Line on Sunday.
Looking forward to your next #tripreport!
