My second Cycle Oregon and first on a fix gear, day 3 was to and around Crater Lake. 8800' and 88 miles. Left camp on a 42-17 with a 23 screwed on the other side, Carried a 12 and chainwhip.
Going around the rim, I passed up a right fork thinking it was a scenic stop. Left fork was a screaming descent to a volcanic bouldered and tilted "meadow" (Best descent yet" Over 1000' and fast!) Saw the meadow and knew I wasn't still in Kansas! (on the rim). Turned around, climbed the 5 miles back up and continued.
I don't know if I broke 10,000' or 100 miles that day. I was way past caring. It was just get me to lunch! Once fed, I was OK the rest of the ride but wasn't about to ride extra 100 yards or 50' up to complete any "goal"
