Is it just a case of keeping going and trying not to stop?
I basically go to the gym 2/3 times a week and am SLOW. I can run for 26 minutes which takes me to 3k, but I can't seem to really build my stamina. I'm desperate to get to 5k but it seems impossible when I struggle to get to 3.5.
Is there any plan or routine I can look at as an example, or is just keeping running going to get me there eventually?
