I hiked a southern portion of the trail- from 24/27 trail head to Hwy 109. It ended up to be about 12.6 miles. At my stage of the game and being in pretty good shape, it kicked my rear end. The weather was cool 48 to 58 degrees and sunny. It was great hiking weather. It had rained the previous 4 days and the creeks were running. I had to hop scotch over many on the rocks.
The ups and downs were moderate for the most part. But there were some that were pretty steep. I enjoyed my trip very much and will plan on going back.
