I need to think of a 12 weel performance goal and I am struggling.

I was thinking about running 5kms but I am not sure I have it in me! 3kms seems like a poor effort
I don't really have anything in that respect i want to achieve (but i dont really think outside the square!)

Do you have any ideas??

*can a mod fix my title please, not sure what happened? performance-ial??? performance goal please*
