My tires were Michelin Pro2Race 25s. Very good tires, fast rolling and long wearing. Unfortunately they don't make them any more. The Pro3Races are much narrower and reportedly do not wear as well or hold up to abuse.
I had patches in my seat bag, but it was a slow leak initially and they are hard to find without pressurizing the tube. I only had one more CO2 left and you can't just use a little bit of it to find a leak, so I took my chances and refilled the tire, thinking I would have enough pressure to make it home. However, the leak got bigger after I filled the tire.
Anyway, I've learned my lesson and put my frame pump back on my bike.
