Does a slow 5k automatically mean a slow mile? I run workouts that suggest Id run a pretty fast mile, and ran a 4:44 on a track just to see where I was about a month ago. Doing 50 miles a week with workouts and weight training, and also ran 8 miles pretty easy at 6:40 pace. But yet I still struggle to hold my 6min tempo for 3 or 4 miles. Why is this? Btw 12x400 with 200 meter jog between each and averaged about 69.5 for each 400. HELP this is my first post on here, I feel like my 5k should be a lot faster and a lot easier.
