I don’t have too much to add here, since you’ve already been given some really great advice – both for the physical and mental aspects of running. Something that I’ve recently started incorporating into my training and growth as a runner is addressing and analyzing the question, “Why do I run?” It sounds like you’re living a healthy, active lifestyle. So what is it that makes you put on your shoes — even on days you might not feel like it? Running is about being active and staying healthy and setting goals for ourselves, but it’s also about who we are as people. While it might not help you with your immediate goals, really knowing Why you run may help you with feeling like you’re in a slump. I certainly know it’s helped me. Best of luck!
We’ve done white clover in our 3 beds, between all the flowers, for the last 2 seasons. We do, still, apply a layer of mulch at first frost but that’s because we’re Zone 4b. I love my clover, I think it fills the empty spaces really well, it’s a nitrogen fixer, so I feel like it’s helping the other flowers, and as long as the other plants are already established, the clover hasn’t snuffed out the “good” plants, just the “weedy” growth. The only 2 things to keep in mind are (1) I found if I plant small/really young plants while the clover is established, the clover will need to be plucked until the new flower has good growth. And (2) the clover itself can get a little wild, but again, we bring it right down and mulch in the winter. Good luck!
