I am from the same general area of PA and did a goat hunt in 2022 in the Chugach Mountains of Alaska. Leading up to the hunt I did a lot of rucking with a 40 lb sand bag in my pack to build up stamina. On days I didn’t ruck, I would do some light trail running or stationary cycling.
I probably could have done more in the woods and off trail, but I did not feel unprepared when it came time to hunt.
Once you’re on the mountain, mental toughness begins to play a bigger part than anything. Just keep putting one foot in front of the other and maintain a positive mental attitude.
I had some level of anxiety when we hiked in from sea level thinking I was not ready. At the end of the hunt, I was complimented by the guide and packer on being in better shape than many guys who come to hunt.
