I also got in less miles in 2016. I'm not completely sure why, but I did not commute as much this year as last, and then I changed jobs in October. The new job has been 50% traveling since then, so the riding time has been getting a bit harder to come by. Along with the traveling comes some bad eating habits. I'm going to try to get back in the swing of things for 2017. I recently finished a 650b conversion, and plan on putting some miles on ASAP.
