Hey Dada,
I’m a guide as well and can appreciate the conflict faced when taking people out and they’re under the assumption that “If I’m not huffing and puffing then I’m not maximizing the experience.” This is often times the same situation when going out w/ friends who aren’t familiar with aerobic training.
(Of course, if your clients are paying you to get their butts kicked in the mountains…then you’re in a bit of an aerobic pickle…)
You’re probably already familiar with this but it may be worth mentioning for others who may be following this thread – before heading out w/ my clients/friends, I set the tone on the expected pace and why (ex. have more energy reserved for skiing, extra margin for the return trip, can do longer distances + multiple days, etc).
Here’s an article that discusses guiding and aerobic base fitness:
