I had completed my warm up and 5 minute walk and had just started to run when I met a friend I hadn’t seen for some time so I stopped to speak to him for about 15 minutes. I was unsure as to whether I needed to repeat the 5 minute warm up walk or just carry on. I decided to walk for 2 minutes after leaving my friend and then resumed my run, but I found it harder than usual.
Any advice would be very welcome!
