The Austin Marathon (formerly Motorola) in February is a great race. The course has changed this year and reportedly is faster than before.
I reside in San Diego now, but recently relocated from the northern Cascades of Washington state where cold temps and lots of snow are the norm for winter training. I ran Austin last year and trained through the winter in sub-freezing temps (a low of 12 degrees and commonly 22 degrees). I did a lot of my tempo runs indoors to avoid slippage, but was able to complete almost all of slower, long runs outdoors (with the exception of one three hour stint on the treadmill). If you have access to trails or dirt roads, they are better (i.e. less slippery) than pavement when it is icy. I adjusted my speedwork to days when the ice/snow melted from the track, except for one ugly session of Yasso 800s - at 2:50s - on the treadmill at Gold's Gym. The muscle boys thought I was insane.
As for training in 10-30 degrees and racing in 65+ degrees, I did not find it a problem, but (obviously) watching hydration on race day will be key.
Hope this helps.
