3 miles in Arkansas

Sat, Sun, Mon- off.
I arrived to Tulsa, OK on Saturday and have spent past 3 days walking around in Zoo, Aquarium etc.

Now I am in Fort Smith, AR with my sister.
I tried running this morning.
Original plan was taking it easy, so I walked 20min to warm it up and then wanted to do something like 1min run, 2min walk but managed only 5x that and then got bored and decided to try running. So I did 3 miles. Knee felt good, no pain. I then wanted to do another 3miles in the evening but felt tingling in the area in the afternoon so no running in the evening.

I will see how it feels tomorrow.
