Please consider making hiking/walking/snowshoeing activities eligible for elevation-gain challenges. Right now, wheelchair is included along with run, and since hiking/walking/snowshoeing are activities done on foot, it stands to reason that they should qualify as well.
I live in the mountains, and it’s a bummer not to qualify for any of these challenges. In general, I would also like to see snowshoeing included in more challenges to the same degree that hiking is. Anyone who has snowshoed can attest that this activity type is no less strenuous than hiking, on the contrary.
