About 50 degrees worth-thankfully on the warmer end here in NC.
Last weekend was the wet and white stuff with temps 15-30. For various reasons I wasn't able to ride for 2 weeks.
I tried to make up most of the riding up this weekend. Stayed out 6+ hours and did a nice 102 miler in 70+ degree weather. With the low humidity and nice temps I kept looking for San Diego city limit signs. Did a little recovery ride today and then worked in 18 holes of golf. I now have a really good start on my tan lines for 2009!!
