Once you start riding them, they are as much fun as the organized rides. I had done so many organized rides in the last 13 years,I sarted to add up the dough I was spending. Did a couple of unorganized with buds then realized, why pay?
In 05, I did 23 centuries. Got to the point I'd just take off and whip out a hundy! Several were solo unsupported, 'just get out there and ride' rides. I'd take $10, G-Ade Powder and a couple of CliffBars.
Nice ride! 5k climbing is great!
