Wednesday medium long run (20km) + 5 x 100m strides

Another midweek longer run. A nice brisk drop in temperature made for 'world record conditions.' Like always, ran based purely on my heart rate, keeping it within the designated 'easy' zone. Managed to average 131 beats per minute, but what was surprising was that my average pace was much faster than usual at 4:18 min/km despite a similar heart rate to what I would normally hold for this run. Can only be a good sign. Finished off with some strides on the grass just south of North Steyne SLSC.
