The Rolex 24 Hours of Daytona is the annual start to the racing year. Other races and rallies may start earlier but nowhere other than Daytona features as many top drivers from different series coming together to start their season. If Le Mans is mostly about cars, Daytona is almost all about drivers. This year's 51st running is the last of an era as we close the book on the Grand-Am years, next year there will be a merger with the ALMS meaning Daytona and Sebring will become part of the same series. Daytona is fast and tough on cars yet somehow it always breeds a close race.
