Don't waste energy on things/situations that are out of your control. What can you control on race day? Your attitude, pace, clothing and nutrition. Check the weather and plan ahead for proper pacing, nutrition and attire. No matter what level of fitness you are in on Sunday, consider where you once were and where you are today. Be proud of any obstacles you have overcome and reflect for all x-miles on race day. If a race (or part of it) gets cancelled or changed, feel good that you have a body that IS ready to race the full distance. No matter the circumstances, thank your body at the finish line as well as giving it a big THANK YOU for letting you get to the starting line.
Also, here's my race week to-do list from the Iron Girl participant guides, to keep you calm, cool and prepared for race day (pg 13 and 14).
To-do list,
