Yes I have; utilizing both road cycling and MTB. When I was training for big alpine climbs, it wasn't uncommon for me to be doing several hundred km/week on the road (mostly LED Z1-Z2) and at times up to 50km MTB. (at a higher intensity) A lot would depend on conditions...
But... I was also incorporating running and rucking. At the end of the day if you want to get efficient at schlepping a pack uphill, you have to do just that...
Right. Hell, I'm not sure I even see that much carryover from running unloaded and on roads and trails to hiking weight perpendicular to contour. Maybe I catch my breath a little quicker on the flats or at the top of the hill, but the hiking still sucks. (Not to issue a recommendation against running, more a purely autobiographical note.).
Now I think about it, I once spent, oh, 6-8 weeks or so doing 7-9h/week of easy Zone 1-2 volume on an Airdyne and a C2 erg to let a stress fracture heal before running Rob Shaul's 6-week Afghanistan program and then going off to work innawoods for a season. It was probably better than sitting on my a#@, certainly helped control bodyweight, and the main volume-limiting factors were boredom and saddle soreness rather than bone stress injuries, but I can't say I felt exceptionally aerobically fit.
