I'm on about the same amount if park runs and time at the moment (158 park runs).
My 5k PB is 20:49 and I was desperate to do sub 20 min.
But then after I got hammered by the OG pre vaccine Covid (and couldn't run for nearly a year) my times sank.
I run the park runs with a friend and dog and we hang back (coz doggo) and chat so it's an easy pace and we tend to come in around the 29 min mark.
He was away last week so I clocked in a 25 min solo park run.
My hamstring/back of leg is also not fixed after nearly ten months (I still run, gym, yoga etc but I think I definitely need it looking at - it isn't going away).
But I'm still desperate to go under 20 mins. Think I need to step up my running and head back to interval training at the club.
Any other thoughts on aiming to beat go sub 20
