#2 yup, upping my intervals now. I think some speed work needs to be much faster than goal, not so much it stresses or injures anything but enough to make goal paces comfortable. As a faster than many RWR I use 4:00/:30 intervals and when running my goal is 7:05-7:10. I’ve started doing quarter mile intervals, run all out looking for 6:00, currently at about 6:20 for 1/4 then jog 1/4 to recover. Doing 4-5 of these a couple times a week for only 2 weeks so far and already noticed improvements. Only time will tell.
#1 is key, consistency is necessary not only for the physical running but when you grind out those runs you just don’t want to do your mental game improves drastically.
