That doesn't sound at all lame to me, especially given what yiu've shared about your other weekly workouts.
I started to do some run/walk intervals myself last week after about 15 months of not running. I don't apsire to being a full tilt runner anymore, but I'd like to add a bit into the mix again. The last time I was consistent about it, I was up to about 10 miles a week with an 8 minute-a-mile pace and was in excellent shape. Assuming my hip cooperates, I'd like to get back to doing 3 miles runs 3 times a week. You've given me some motivation. Thanks!
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
