I'm trainin with 50 pounds, 4.6 miles in 2.5 to 3 hours, 670' of climbing. 4 to 6 times a week. This is an out-and-back trail, with mostly gentle, short ups and downs, till you're close to the end.
Then, as I'm halfway up the mountain, it's 75 steep feet to the bottom followed by 150 steep feet to the top - which I repeat before continuing - down a ravine leading to a steady - maybe 45 to 55° -200' climb, then back down and around to the backside of a hill - the "Grande Finale" - a steep and somewhat treacherous 200' climb.
Except for grande finale, I try to do all the hills mentioned in that last paragraph without stopping to catch my breath. The 1st two, the 150' ones, I'm doing in slow, tiny but continuous steps till I get to the top. Usually my legs are burning at the top, but I'm not too out of breath.
On the next hill I also go continuously till I get to the top, and stride is a little bigger than before, as this one isn't quite as steep. When I get to the top this time, not only are the legs burning, but I'm also breathing hard.
Fortunately, there is a good place for sitting at the top of this one.
Once I've recuperated sufficiently, I head to the "grande finale". That one, I have to do in sections. The first part is steep, and I have to climb steadily, carefully finding the footholds until I get to where the angle drops a little. Gotta stop there, catch my breath, let my legs rest as good as I can standing up with 50 pounds on my back. Next is what looks like a third to a half of a football field, of more gradual uphill, followed by very steep (I don't know if it's 70° - it's close to the steepest angle a normal person can climb without climbing gear) - 25 to 35 feet.
So, I make my way to the beginning of that last steep part. Stop again to rest my legs and catch my breath. The last part up, there will be no stopping, once you get started. Your position at each step along the way is too precarious to linger.
When I finally make it up, I scramble to the shade of a huge oak tree, and I would love to just collapse and rest for a few minutes. But don't want to take the pack off, since I don't want to have to pick it back up again. So , I rest there, standing as best I can.
From here, it's a mile and a half of mostly gentle ups and downs back to the parking lot. At this point, tho, even some of the gentle ups are challenging.

So here's my question : Isn't this supposed to start getting easier at some point???
