Rules & Guidelines Day goals, break days, and badges

Each day is the # of KM you need to complete by the end of the day.
You can split up the KM in the day. Example: 5 KM in the morning, 5 KM after work.
If you need a break day, that’s ok! Mark it down. We understand.
Badge rewards: Festive Finisher (free) for 12+ days logged; Run-mas Master (Pro) for completing all 300 total (a run on every day 1–24). Find them in your Profile Badge Gallery.
