We're just hours away from the start of the Rolex 24, one of the biggest endurance races in the world. The action kicks off from Daytona International Speedway at 2:40PM ET, and the race will last through the night until — you guessed it — 2:40PM ET on Sunday.

There are a few big storylines to watch this year. First and foremost, the LeMans version of Ford's revitalized GT supercar makes its official racing debut. (Consider it a tuneup for this summer's 24 Hours of LeMans, which will mark the 50th anniversary of the original GT's incredible 1-2-3 finish.)

Another thing to watch is the bizarre DeltaWing, which debuted at the 2012 LeMans race. The prototype-class car had trouble competing in the following years (and was even the center of a messy legal dispute with Nissan) but has looked strong in this week's practice sessions.

This is an onboard video from the DeltaWing earlier this month at Daytona. Driver Andy Meyrick actually passes the Ford GT in particularly hair-raising fashion at 1:06.

The full schedule for the Rolex 24 can be seen below. The broadcast will hop between Fox Sports 1 and Fox Sports 2 every few hours, but the 10PM ET - 7AM ET overnight stint will be broadcast on IMSA.com (along with the remainder of the schedule). You can also listen to the full 24-hour radio broadcast here.
