I haven't done it all in one day, but I have done 150 of it in one day. Vibration killed me on a rigid steel bike with drop bars running Continental Tour Ride 700c x 32's with 70 lb. pressure. It worked OK, but I'd pick 37's if I did it again--ruts, loose stuff, and transition from trail to driveway crossings are snakebites waiting to happen. I'd recommend gel insoles, gel gloves, gel seat, gel bar pads. Since it's flat, weight is not a problem. Check the weather for prevailing winds: You would probably prefer to go west to east. Other than that, trail mix, CamelBack, powdered Gatorade, eat before you're hungry, and drink before you're thirsty. Good luck.
