Group ride up one of the famous Cols in SoCal,
Lytle Creek. I had my race wheels on and flatted going up, spare flatted as well and no one in my selection had 66+ mm tubes. I walked 3 miles down the mountain until I got cell reception and got a ride home.
I planned to do Raincross but my teammates planned this one instead. Would have taken training wheels if I knew; that road is nothing but shale, glass, and auto parts.
Now I don't know if I'm going to ride again since I came well short of my planned TSS.
