I'm new to this hopefully someone can explain to me . I saw each day after work-out you get the point everyday [+!1,+2....] in calendar, but I not see my level go up unless you get new badges. so that point you get each day mean anything?
The 50 or 100 miles in a single activity badges are just as they say, you must go that distance in one activity of the specified activity type. While it sounds like a lot those distances are achievable by some.
