Hi Pete,

i would say you have three options.

1.Keep doing as you are and the fitness and distace will come i promise!

2.Reduce your pace and you should be able ot run longer.

3. Mix it up and do a couple slow and a couple fast(but short)

Whichever you do if you run 3-4 times a week you'll find 5k a breeze by the end of May if not before.

BTW i favour 1 or 3.
