Running Diary, day0008

9th Dec 2013, 23C, sunny.
Started at 6am, tried to maintain HR below 130bpm, finally ran 12.4km in 1:29. It was hard to control the pace below 7:00/km after 6km if maintaining the high cadence (I think >180). And also hard to have HR dropped below 110bpm no matter how slow pace I make. It seemed long way to achieve my supper recovery, ultra running goal.
From tomorrow, I'll walk the final 300m of my running routine (from the last traffic to home) to monitor HR recovery rate. It should be a key index for aerobic fitness. I saw Suunto provide this kind of data output.
