No idea about their algorithms, but I have never gotten a swimming challenge before despite swimming regularly every summer. If I were to guess, I'd say it requires six months or something of a particular activity for it to be eligible for a monthly challenge.Why couldn't I get that during the summer. You know, when the water was 90° and I swam for an hour every day.
Best of luck!17 move goals for me... I'm literally spending a day and a half in the air and a week at conferences this month, have thxgiving of daddy duty... in other words, it's gonna be an effort. Last year I ran 100km in Nov. This Nov, I'm def' not in the mood for such.
