I rode 108 miles on Saturday using my Tarmac. 8000+ feet of elevation gain and some gnarly descents.
So, I make it all of 12 miles out of 28 this morning on my touring bike and my rear tire's casing completely failed. Tried to boot it and blew out my spare tube. Then walked a few miles to the light rail station. Oh well. Such is life.
Going to take my tires off of the Tarmac and use them instead. Time for the next Tarmac upgrade I had planned.
