Brisk Walk at 8km/h

Today, I change my training to brisk walk at a target speed of 7:30/km. I use the Stirling loop as well and make two loops around it for a total of 6.67km.




The training is not easy and maintain heartrate at >150 bpm. At the end of it, I did very fast dash at 5:30/km. The Stirling loop has ups and downs. On a flat course, I still have room to go slightly faster, possibly at average 7:00/km for a 5-6km dash.
