Just looked at the alminac on wunderground for the date of the Novmeber race. Looks like it was cold on that day last year- like in the 50's and 60's. But in the 05 and 06 it was in the low 70's. Last year still had a bit of wind, but not nearly as bad as yesterday. BUT a big thing I noticed was the sunrise and sunset times. Sunrise is 7:06 am, and sunset is 5:21 pm.
The swim starts at 7:00, so I wonder if they are going to change that. Also the bike cut off is 5:30. With sunset being at 5:21 I imagine they will have to change that. My guess is there's going to be stricter cut off times.
