Ran my first "early" (07:20 start) morning 10k on Sunday and it was hard work. I usually run at lunch time or in the afternoon and it just felt like my legs were made of stone, I was way off my usual pace.
Also not sure what to do about food at such an early time, especially when I want to start going longer than 10k. I obviously need something to eat but if I have too much then I'll have to wait a couple of hours to feel comfortable. I just had a single slice of jam on toast and it was probably enough until about 8 or 9k where I really started to flag. What do people do?
