I am mostly concerned about the peripheral stuff, rather than finishing the 140 odd miles. Are my spares and tools adequate ? Is my bike set up OK ? Have I packed the right gear in my Bike/Run bags ? Is my nutrition plan OK ? I know my preparation was right, and I can go the distance, but I am starting to think more about times. I am fending off the inevitable goal inflation. Stick to the original plan ... you are aiming for sub-12 hours. That's 12, not sub-11, definitely not sub-10 and most definitely no where near a Hawaii qualification ;-)
Dinner in 1 hour. The last big meal before the race, and with any luck the last time I will go anywhere near pasta for a long time.
