How to recover legs ?

Sleep more. Eat well. Hydrate.

Maybe slow down some or all of your running?

But my goal is to run faster

I can say with certainty that running with legs that are always sore is not going to get you where you want to be.

Rest. Your body is telling you that you are doing too much. Listen to it.

Good grief.

Does having sore legs make you faster?

The way to cure sore legs is to...wait for it...REST! Shocking, I know.

Then run your hard days hard and your easy days easy. Really easy. Don't monitor your heart rate. Don't worry about what "zone" you're in. Just run easy. Easier than you think you should.

Is your goal to run faster in races or to impress people on Strava? If the latter, I suggest you delete your Strava account.

First you need some new legs.
