Two questions! First, does location count? Metro area, cold climate, etc? I am not going anywhere
so I won’t be riding in a warm locale this winter, but in principle is there a restriction? (For that matter, a strict interpretation of the theme of this event would suggest that none of our rides on this balmy New Years should count! 
Second, does the calculation mechanism account for multiple rides in a day? I will on occasion do a ride with my daughter and then later (or earlier) do a solo ride? Seems unfair to restart the point count at 10 for the first mile twice in one day. I presume the calc works on daily total miles but am just checking.
Have a great day, all!
