4 miles today while I loosen up a stiff back and push tempo for a 1 mile to wrap up. Tweaked my back something bad yeaterday and got stuck on my bedroom floor in awful pain for a minute 😆🤦🏻‍♂️. It’s hell being 40, they say, but I refuse to believe so we push on instead. Nice cool temps for the short cruise today. #runningvlog #runningtok #running #denverrunning
