      If you're looking to see if lefthand is right for you, this is a good second step. Much steeper climbing...

      Super loose and steep. It’s mostly walking your bike up
      Jrhockney
      Just did this for the first time today.. It's hours later and I'm still out of breath ;p I probably only rode about half of it while actually on my bike... maybe if I was in spring shape I could ride 70% or 80% of it. It may not be super long but it is mercilessly steep, fairly loose, and even a bit technical in a few spots... But a big payoff at the top with multiple great downhill runs available.

      We hope you've been enjoying Trailforks!
