Walked 3.6 miles. Knee is sore, but the doctor says I need more muscle so it's worth it.

Bit of sore and tired is good. Occasional, "oops I over did it" is not a terrible thing. So, it sounds likely pretty decent.

Nice!

Well done you! Starfirez: and you, too!

That’s a good long walk, especially with a hurty knee.

good for you
