This is a provisional hike lead for Katja Hurt, please direct any questions to her.

This conditioner will be timed for completion to help participants in the Olympia Basic Climbing Class complete their third hike for the optional conditioner challenge. Other hikers are welcome to attend, however, please be aware of the following:

  • Our goal is to reach the summit in three hours or less with medium effort (we will keep the heart pumping but still be able to enjoy ourselves).
  • We are aiming for a sustained pace with limited breaks (a short break in the first 15-20 minutes then one short break per hour).
  • Minimum pack weight is 25-35 lbs (best pack weight is 20% of your body weight).

If you are unsure of your ability to meet the conditioning requirements of this hike, please contact the trip leader. 

Plan for variable trail conditions (mud and snow/ice on trail) and try to layer in a way that takes less time for adjustments (zip-ups rather than pull-overs, jackets with vents, gloves/hats easily stowable, etc.).
