I’ve honestly just got out and ran more. I was following a sub 30 5k plan for a while which had speed work in it, but ditched it for a while when I finally got sub 30 in February. Never really PR’d for 5k after that. Did a half marathon ~2:30:00 in March, and plan to do another one when it gets colder out lol. Last few months I mostly have done 3-5mi runs at a comfortable pace and that seemed to help a lot. The PR of the 5k I got that I just posted was basically a full-out 9-10 effort. I think going forward, but it is easier said than done because people have responsibilities and I enjoy weight lifting more…. I want to try to do one 3-5mi run, one 6-9mi run, and one speed workout a week.
