The performance boosting benefits of smiling have been a hot topic ever since Kenyan marathon star Eliud Kipchonge was spotted deliberately grinning to himself every few minutes during Nike's Breaking2 marathon last year. A researcher in Northern Ireland subsequently published a study showing athletes becoming more efficient, burning two percent less energy to sustain a given pace when they were smiling. Personally, I feel totally exhilarated while training on land or water. With championship rowers, it's not about one plus one equals ten. The greatest crews have an ability to make one plus one equal magic. It's that intangible aspect of the deep commitment to each other and to the greater purpose that accelerates the shell through the waves.
