I started hiking in 2014 so I could get in shape to hike Mt. Whitney.  My first hiking challenge was the Adventure 16 Three Peak Challenge in 3 months, which I completed in 2016.  Then in 2017 I completed the Three Peaks in 3 weeks.  In 2018 I hiked the Three Peaks in three days, and added three of the other big mountains so I could finally say I completed the Six Pack of Peaks Challenge!  Now I like hiking new mountains as they are added to the Six Pack Challenge.
