I had a commuting goal of 3,000 miles but fell short . . . and checking my records (yeah, I keep an excel spreadsheet) I commuted 140 days in 2015 @ 19 miles per day which comes out to 2,660 miles.
I only commute Mon./Wed./Fri. since I have club training rides on Tues. and Thurs. evenings. I missed a few commute days but not many.
I thought there was a way to check on Strava to find out how many commuting miles they show for me but now I can't find it.
My totals for the year so far (won't change much now!) are: Total miles: 12,238. Total feet of climbing: 905,545.
Total centuries 33 (counting double centuries as only one) and eight doubles.
Overall a good year; a couple of weeks lost due to sickness but thankfully no bad crashes or serious long-term illness issues.
