2.7 miles easy then 2.7 mile cool down

Mom and I did 2.7 miles easy on the beach and then a 2.7 mile cool down walk, also on the beach. My ppm for the easy jog was 11:17. Bad left knee, now bad left ankle, and overweight equals slowness. Thank goodness I have 3 months to the Asparagus Run. Mom did the entire 2.7 mile easy jog, a little slower than me but not much.
