Today's 11m MLR is done and dusted on the treadmill 
Planned pace: 10:48 to 9:54 Planned Heart Rate Range: 141 – 160 bpm
Splits: 10:43/10:31/10:22/10:20/10:21/10:10/10:00/9:50/9:50/9:50/9:50
HR: 122 / 132 / 138 / 141 / 143 / 146 / 148 / 151/ 153/ 154/ 159 bpm
I gradually increased the incline on the treadmill in the last few miles in order to get to the top end of the heart rate range, without going over the planned pace. Quite a good simulation of the last few miles of my regular outdoor route.
I hope the ice clears by the weekend. I really don't fancy 18m on the treadmill
However, needs must when the devil drives
