Hi
I spend most of my runs trying NOT to concentrate on what I'm doing (other than occasionally checking my form and my breathing), but I found 10k mentally tiring. Not from fighting the demons although tbey were there, but like I'd been concentrating for a long time. Physically all was well after 30 mins or so, but mentally was awful. I went out with a friend after to celebrate with her and couldn't find my words in French to speak to her (I have been speaking fluent French for over 15 years lol).
Does anyone else get mentally tired after long runs ? Any tips ?
