I just Set a PB on My 10K Cemetery Hill Course!

It's all looking good for my first sub 40 minute 10k ever, and at age 52 for God's sake.What could go wrong?
  I hammered out a 43:28 with lots of hills, tons of rain, a strong headwind and I was not throwing up tired at the end. I ran a 41minute something Sporting Life 10k about 10 years ago at 185lbs. Let's see what I do around 155 lbs.The Sporting Life 10k is known as the country's fastest, right down Yonge Street, mostly downhill from North Toronto to the Lake. I can run to the start line in about 15 minutes.
  Now tomorrow's going to be another story. Let's see how the endurance is. The Fat Ass Pylons are going 3+ hours of technical trails in Hilton Falls,and I know the Captain is going to head out like a rocket. He and Phantom have the "Fools 50k" coming up in Ohio in a couple of weeks.
