analytical runner

So... 10 more days till race day...

Being underprepared.. i can't help but to plan the "strategy"... and by strategy i don't mean, start running now for miless....

I'm planning my time so that i can actually finish within the allocated time. After starting calculating.. so here is the plan

first 7 kms ---> pace is 8 mins/km
second 7kms ---> pace is 9 mins/km
thirds 7kms ---> pace is 10 mins/km

This plan assumes that my energy will depletes after 7km.. So now the first step is up, I gotta identify where is the above points? anybody has map with the km points????
