Fingers crossed is a common strategy for race day.
Hoping for a performance that your training indicates is unlikely, that the weather is 'normal', that the energy drinks don't upset your stomach, that your new running shoes give you a couple of seconds a mile rather than blisters...
On the other hand, preparing appropriately is far more likely to be a winning strategy.
Doing the right training at the right time, practicing in different weather conditions (especially extremes), testing out the energy drinks and wearing in your new shoes before the race.
A little preparing beats a lot of hoping.
