My second training hike of the day was a 9+ mile journey between Thunder Rocks and Mount Irvine. The net elevation gain was < 100 feet, but the cumulative elevation gain was over 600 feet according to CalTopo. There were lots of ups and downs on the #2, #1, and #6 horse paths that I used.
Having lost 20 pounds since the end of last year, I'm hiking with a bit more giddy-up than I have in recent years. It feels good. We'll see where I'm at in the second-half of the year when I'll be taking on bigger peakbagging objectives than I have in a long while.
