Wow, I amazed myself. Lord knows I needed a great day, my endurance and pace have been suffering lately. And my 4K is tough for me to improve upon, since my old time was fast, but I bettered it by 5 seconds. AND THEN, fifteen minutes later … I surprised myself lowering my mile to 6:31 (an 8 second improvement). I still can’t believe I had enough left in the tank after those grueling, energy sapping four kilometers?! Oh, and am also surprised since it’s very humid (feels like 30°), and the air feels so thick, making breathing difficult. Like I said, wow … chuffed again!
