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

It was actually warm and humid this morning. I was actually sweating in my t-shirt - that hasn't happened since about February, and it's still winter! 20km nice and controlled, averaging 129 beats per minute at 4:24 min/km pace. Reverted back to doing my strides on the grass today - a bit uneven but I seem to pull up better the next day compared to when I do them on the concrete.
