Thanks very much for that helpful response, Mark. I bought the 24 week plan and it turns out that there is an option to either run OR hike. Running isn’t mandatory, and that helps a ton. Looking forward to training. Thanks again!
Just one quick follow-up. Is there a particular ratio (re time spent) I should use while substituting another aerobic exercise for running? If the program says run for 30 minutes, and I’m using the stair stepper or incline treadmill walking, should I do that for 45 mins? An hour? Many thanks!
Many thanks for your responses. I’ll experiment with different cardio, including stair stepper and start incorporating daily strengthening workouts. Hopefully that should resolve the issue by the new year. I should note that I’m preparing for a 12 day mountaineering class, and not an actual Denali climb. Hopefully that provides somewhat more of a wiggle room to push running and other intensive cardio a few weeks back. Thanks again!
