Legs or Fingers?

I'm in real trouble. I've booked my IPPT on the 23rd August Khatib Camp. That's like less than a month away. And my 2.4km timing is a geriatric pace

ish .... I'm too shy to put this .... 13.19mins

Is this the result of practising too much on the guitar? You gain some you lose some. If you keep practicing scales and arpeggios your fingerings will improve. The same practice principle ought to apply with running and stamina.

Now if only I could find the motivation to run.
