I had seen a post in FaceBook (FB) and signed up for this today:
I had done the 5k everyday for the month of February. I did miss 3 days but did extra miles later in the week so that the miles would add up to same amount of miles by the end of the month. For this challenge the breakdown is 3.61 miles per day or 25.27 miles per week. I will need to submit your mileage monthly as long as I stay up with the mileage I should be ok.
