Okay... stay with me now cuz I'm hoping one of y'all can help.. I live in the flat lands.. but an old college friend and I are going to the Grand Tetons and Yellowstone for a "girls getaway".. uhhhhh and we're in our 50s.. and she's rarely camped much less backpacked.. and I'm a walker and hiker on flatlands with some backpacking experience in Arkansas and Washington State.. but don't have mountain experience (especially at high altitudes) other than reading, watching you tube videos, etc.
I went for a short training hike on an 8% grade over 6 miles in an attempt to get some elevation (don't laugh I had to drive several hours to find that!).. and I had no problem going up but going down hurt like the dickens. My calves were on fire! I ended up walking backwards to relieve the pain. I work out a lot.. lift weights.. do HIIT.. do long slow walks with some running.. but...
So, my question is this - How in the world do I get my calves ready for the downhill in the Tetons?? I have tried everything to replicate the feeling and I got nothin'..
Any help is appreciated..
