Today I learned my lesson...I should have payed closer attention to you veteran walkers and all your advice regarding ruthlessly paring down the pack weight.
I walked 19.3 kilometers with an elevation gain of 434.8 meters wearing a 6.4 kilo pack (inclusive of 3.5 liters of water - no refills along the route). By kilometer 11.27, I had decided to replace my 820-gram sleeping bag with a 170-gram silk liner and to eliminate a 297.67 gram long-sleeve shirt. By kilometer 14, the 552-gram Tevas as alternate hiking shoes/evening shoes were mentally tossed out the window in favor of a 302-gram pair of Croc-like shoes. Oh, and by the end of the trail, I'd decided to return the 46-liter, 1.5-kilo pack and keep the 36-liter, 1.27 kilo pack.
The thing is, carrying that weight was "do-able" but I realized I had no desire to "do" it.
Thank goodness it was a practice run. I'm a believer.
