Starting in July of 2015 I made a commitment to get back in shape. After a few months of walking, running (ugh), and P90x-type videos I remembered my road bike, hanging neglected in the garage. Towards the end of 2015 I started riding a little more regularly. Spring of 2016 I experimented with commuting to work (25-30mi roundtrip, depending on exact route). Experimenting soon led to a pretty regular thing. Around the same time arbitrarily picked 4K miles in Strava as an annual goal, which I achieved at the end of November. Without the 90-150 weekly miles that commuting nets me I wouldn't have come anywhere near that goal. Shooting for 6K miles in 2016 by trying to have more 4-5 days/week commutes instead of 3 days/week. Along the way I've also acquired another 4 bikes and lost over 50 pounds. Yay commuting.
