I booked a four-day hut-to-hut hike for late summer back when I was 31 lbs heavier and assumed the GLP-1 curve would do the rest. Weight-wise, I'm down about 29 lbs since January, and my blood pressure has been friendlier. But last weekend I did a 900-ft local climb and had to stop twice.
In the trials, the average weight loss is impressive, but I don't think that automatically translates into cardiorespiratory fitness. I've been lifting two days a week and walking, but mostly flat. Now I'm looking at 8-10 mile days with a pack and wondering if I should train zones or just practice being humbled.
Anyone else book something before their cardiovascular system caught up? What helped — hills, intervals, pack walks, or just lowering expectations?
