Inspired by other posters who have done, I wanted to break my personal distance record of 38 miles by doing the Gen. Van Fleet trail. I started at the Mabel trailhead, all the way to Polk city and back. The odometer says 60.17 miles in 5:52h. To that you could add a 20 minute break at the Polk city trailhead and another 5 minutes at one of the middle stations (water comes in, it has to come out).
And since my current road bike doesn't really fit me, I did it on a (drum roll here...) $59.95 cheapo MTB from Walmart that weights 51 pounds and has both wheels out of true.
My only regret was not taking my camera with me. As expected, I found lots of squirrels and 2 snakes. But the bunny that tried to race me for 1/10 of a mile was a new one. The deer that jumped in front of me was very pretty and unexpected. And I really wanted to get a picture of my exhausted self, flipping the bird at the nasty looking vulture that was circling above me for the last 90 minutes (I'm not dead yet!).
I feel great!
PS: The bunny won...
