my age brackett it's 12:38 1.5 miles .. i've just never been a runner so its harder than i thought.
I think you are correct about the mental barrier..
If we're talking about 20 seconds then it's really just a question of willpower.
What you could do is not train during the week you're supposed to do this test, or taper down (ie do less volume/no high intensity).
You will be taking 85% of your energy from your glycogen system for a run like this, therefore, I would advise to load up on carbs a bit a day or 2 before the test. Don't go too overboard though, where you aren't an endurance athlete you likely don't have as volumous glycogen store.
