A comment by DiscoRunner reminded me of Dr Tanaka's slow jogging. This morning, I decided to do a slow jog instead of my usual 5k. I ran 4.2k at 7.1 min/km (my previous 5k was at 5 min 2 seconds pace!). My heart rate initially rose to 131 bpm but settled down quickly to give an average of 111 bpm for the 30 mins.
So how was the slow jog? In short, wonderful. It was great to jog along with a stride length of (only) 83 cm, breathing through my nose and enjoying the sunshine, the butterflies, the wild flowers and my music. I highly recommend it to anyone looking to enjoy your running more or wanting to introduce some variation.
