Chill out as much as possible in the last few days before your big race. Yes, you've done all the hard training earlier and it's now down to the last week. So don't be afraid to rest more now.
Reduce the outside stresses in your life especially from work. Try to have all your work projects under control.
Decline politely all invitations to any late nights out and so on. Try to stay off your feet as much as possible in the last few days.
For those of you collecting your number tags, fon't spend too much time at the expo after collecting your race entry pack. Now is not the time to check out the latest running shoes or energy gel flavor.
You can carbo-load but don't fat load, especially in the last 3 days leading up to the race. And remember this, since you have already been tapering and thus expending less calories you don't really have to eat more than usual.
Stay tuned for one more post just before race day.
