Thanks to a combination of a very actively nocturnal cat and some determined mosquitos, I'm fairly permanently sleep-deprived at the moment. And living on a boat in the south of Spain, it's much too hot to run during the day, so we head out in the morning before sunrise to take advantage of the coolest part of the day.
Starting a run when already tired, though, is hard work! It was W7R1, and my legs already felt like they'd been running ten minutes when I started. I was very much flagging by the halfway point, but determination kept me running until suddenly, about three minutes before the end, I felt better. Much better, and I was able to pick up the pace again - from about 5 miles an hour to 6, according to my tracker. When Laura told me to try and run faster for the last minute, I grumbled at her that I already was, and I ended my run feeling pretty good!
Is this normal? Or, arguably more importantly, does it only come at the point of exhaustion?
