According to Strava, I was comfortably past my running distance goal of 400 miles for all of 2018. I show a total of just over 412 miles, which is great, and just a little more than last year.
I've had that same 400 mile goal for two years now, and it seems comfortable enough. The stretch goal for my running aspirations is in the weekly. There, I have a weekly goal of 12 miles, which I sometimes hit. It's not physically difficult, but usually amounts to an issue of time: Do I have the time to do it this week?
If I were to hit my 12 mile week for the entire year, then assuming 52 weeks a year, I would hit about 624 miles in a year.
But again, 400 miles for the year is comfortable, and very much doable. So congrats to me!
