Although a different type of advice, try to chill as most as you can (or not work you a r s e off) during those 12 hours/7 day schedule.
Your stress level is going to be higher, so try to find some type of relaxation to even things out. Work on your diet, no junk food, no sodas, cut on sodium, sugar, processed foods, etc, it does makes wonders. Monitor your resting heart rate, sleeping habits, etc.
Dont max out at all at least one to two weeks before the race, and dont try anything new (like clothing, shoes, sports drinks, bars) on race day. Dont go crazy on high end gear.
