You can challenge yourself to daily, weekly, monthly & definitely yearly miles. I enjoy having both daily and yearly goals. It's easy to keep track of and it keeps me motivated to keep moving through the winter months & lazy periods. I wear my fitbit all day long and record both exercise plus daily movement (but you can record whatever you want to).
My daily goal is 10,000 steps or 4.5 miles (I post these on my home calendar).
My yearly goal will be 1,642 miles, which for me is 10,000 steps a day x 365 days (which I will make a 2018 ticker for and update total miles for the year several times per month throughout the year).
Join us anytime in 2018, have fun & KEEP MOVING!
