Daytona 5K
It was a perfect morning for racing (a little humid, but you'll have that in Florida
). 42°F with a crescent moon and Venus in the sky at the start, next to no wind. The economy meant that there were far fewer campers than usual for the 24-hour sportscar race. Bad for the Speedway, but good for us runners, since we didn't get the usual blast of campfire smoke as we rounded NASCAR Turn 3. Interestingly though, the field of runners was larger than past years, over 1,000.
Somehow I managed to set a new PR by over 40 seconds, at 24:25. Must be good grip on the new pavement. 
Tough competition this year, though, 5/44 in age group, and at least one runner who perennially kicks my butt was a no show this year. The woman who won the 50-54 age group ran a 20:55.
