Went out for an easy couple of miles barefoot, then decided to throw on my Vibrams and see what I could do. Was surprised to find the hill climbing much easier on the legs, lungs, and heart (thanks, Big Sur.)
Also! Ended up meeting my climbing goal for April. Climbed 1,823 meters in April. That's 3 months down on my goal of setting and completing a climbing goal for running! 3 months to go!
