My plan tells me 8 miles at race pace for Sunday and two 2 miles tempo runs during the week plus a mile wsrm up and down either side. My legs don't seem my own since I drastically reduced mileage two weeks ago. I did and complete to plan a fast tempo run last night and although I wasn't out of breath my legs didn't want to turn over quickly enough. I think I've lost all my fast twitch muscles!
Distance running in the 70s was never a big thing at my school, apart from a few cross countries each year when the football and rugby pitches were waterlogged. It didn't stop the great Nick Rose (who held all our school records from 800m upwards). He got all his training from the local athletics clubs. Most of the sports teachers were into their rugby and football, so they used to let you loose on your own to run wherever!
