I’ve set a running goal for the 2019 calendar year — to run 2019 (or more) miles.
I ran 1,638 miles in 2018, which averaged out to about 4.5 miles per day. That means I need to up my yearly mileage by about 380 miles. A fair increase, but certainly possible provided I can keep from getting injured and/or sick.
With some basic math — 2019 (miles) divided by 365 (days) — I find I will need to average about 5.5315068493 miles per day. To keep that a bit simpler, and to ensure I go over as opposed to under the goal, we’ll just call it 5.55 miles per day.
