After 12 hours of racing, Max Angelelli in the #10 Visit Florida Cadillac DPi leads the race overall by a lap over Rene Rast peddling the #90 Multimatic/Riley LMP2. Third spot in the Prototype class (and overall) was held by the pole-sitting #5 Mustang Sampling Cadillac DPi. 

Despite the persistent rain the official attrition rate remains low with only 5 cars currently showing as withdrawn; #24 BMW (gearbox issue), #2 Lexus, #59 Porsche (oil line), #16 Lamborghini (2 heavy accidents), #73 Porsche (hit by Oreca into bus-stop causing a triple impact) and the#51 Ferrari (untraceable misfire). 

Both Action Express Cadillacs hit problems at the start of the night running with the #5 Caddy suffering another brake light problem forcing the team to replace the rear-end for a second time in pit road. The sister #31 car lost six laps following lengthy repairs due to an incident with the #88 Starworks PC Oreca caused problems with the steering wheel and starter.

In the GTLM class the new-for-2017 Porsche 911 RSRs held the top two positions with Kevin Estre leading the pack in the #912 from team-mate Patrick Pilet in the sister #911. Joey Hand in the #66 Chip Ganassi Racing Ford GT trailing the Porsches in third. 

The ever present Prototype Challenge pack were split by some of the fastest GTLM cars, the #38 Performance Tech Motorsports Oreca FLM09 leading the class followed by #20 Gas Monkey sponsored Oreca of Bar1 Motorsports and the #26 Case-IT sister car. 

Moving to GT-Daytona, the all-new-for-2017 #86 Michael Shank Racing Acura (Honda) NSX GT3 led the pack from #29 Montaplast by Land-Motorsport Audi R8 LMS GT3 from the Riley Motorsports Merceded AMG GT3. 

The rain continues showing little or no sign of slowing down.
