I have run a 3.06 five weeks after running a 3.06, and still haven't cracked 3 hours, a year later with no injuries.
Best to date 3.01. I have learned that going the extra mile from a 3.06 to a 3.00 is a big step up in class, much more difficult than I ever expected.
I suggest a slow easy one and don't push yourself. Enjoy the day, and regroup for next year.
Better to be running crap than not at all.
