I am due to do a half marathon in 3 & a half weeks time
I have completely lost my confidence and not sure what to do...I'm seriously thinking about throwing the towel in for this one.
Had a horrendous run on Sun - just awful. Tired, sluggish and legs v tight. Was supposed to do 9 miles & did about 6. 
I'm stressing that I won't be able to do it. I've done 2 halves in the past and by this stage was comfortably doing 9/10 miles at a reasonable pace. I'm heavier this time and I haven't trained as much as I could as work has been mental so think I've got a bit of a downer on myself.
I never think like this - I think I've lost my confidence. I know that mental attitude is so important with running - is there anything I can do to get my mojo back?!!
Any inspiration? Or should I knock this one on the head? I've got other runs booked for later in the year. I wonder if part of me is thinking that I've run (haha, no pun intended) out of time for this one.
