Most likely, you won't get great sleep the night before your race. You will have probably tried to follow every little bit of advice you have received, but unfortunately everyone had different opinions: "Eat lots of pasta the night before," "No, you need meat!" "Stay off your feet," "No, go for a nice long walk." "Take a hot bath," "Take an ice bath." "Stretch." "Don't stretch," "Eat bananas the morning of," "No, oatmeal." "Stay away from coffee." "Are you out of your mind?!! You need coffee!"...
Well, I can't give you much advice here. There are many opinions about what helps and what doesn't, and you will have to learn in time what works best for you, but I will give you just a few basic tips that might help:
1. Trust your training! At this point, there is really nothing you can do to be more physically prepared than you already are for your race, so don't sweat it. If things don't go well, you will just have to train harder for your next race. If you know you are not ready to race, treat it as a "fun run," and don't even try to race.
2. Too late to try anything new! It is wise not to try any foods that you are not used to eating or any new stretching exercises or whatever. The last thing you want to do right before a race is injure yourself or be sick during the race and have to hide out in a porta potty! Stick with what you have been doing on your regular training run days, and keep it simple. This also applies to race strategies. It is very tempting to change strategies at the last minute and second guess your original plan. It is much better to stick with the plan. If it doesn't work out for you, you can change it for a future race.
3. Eliminate surprises! Of course it is impossible to prepare for every little thing that could go wrong, but knowing that you have taken care of the most important things will go a long way in helping you relax and get some rest befor the race. Here is a basic checklist:
-Double check time of race and directions to race location -Car is ready (gas tank full, air in tires...) -Race bib is pinned to shirt (if possible) -Bag packed with necessariy supplies and extra articles of clothing -Cash for race fee (if needed) -Review race course (if possible) -Check weather and prepare accordingly -Alarm set properly (maybe set two alarms for peace of mind!) -Pray (for safety, peace, and ultimately for God's will to be accomplished)!
