I set a new PB in the ZL1 at Roebling. I wound up running a 1:17.28 on an early lap. The predictive timer was clearly showing a 16 until I overcooked turn 9. Blah. As the day continued, I cleaned up my line a little, but heat and traffic kept me out of the 16s. The timer that I have said that my optimum time (putting my best segments of the day together) would have been a 1:16.2. I know it's in there, and I will be out on fresh rubber with cool air and less traffic in front of me next time. 16s are guaranteed. Can 15s be had? Stay tuned...
