The last four weeks have been all on the treadmill. Since November, the mileage has been 43, 54, 57, 34, 42, 52, or around 46 mpw. I've still had a sore lower back and left periformis muscle, but aside from three weeks ago, when I took three days off due to travel, the running has been consistant.
Each week has a hill workout and a speed session. After a 19:07 5K race, on what felt like a good day, I realized I needed to do at least SOME speed work.

Most of my runs are around 8:30-7:40 pace. But the speed is a good use of the TM.

My next race won't be until March 30--a 30K--so I don't need long runs yet.
