1 run per week - optimal 5k training strategy?

[TheEd]

To be truthful, doing 3 x 1k or 2 x 2k

does not really help in the development department

consider 4 x 2k with Rest 2 minutes

and

5 x 1k Rest 75 sec

obviously at a slower pace but you will gain more than simply running fast

hopefully you understand where I am going with this
