The eighth running of the Historic Sportscar Racing Classic Sebring 12 Hour, Pistons and Props, presented by the Alan Jay Automotive Network, hit the halfway mark early Saturday evening as darkness fell on Sebring International Raceway.

Each of the four competing Run Groups have completed the first two of their four race segments that will be run over the course of Saturday and Sunday, and a mixed group of potential first time winners and previous HSR Classic 12 Hour champions has emerged as the race leaders at the halfway point.

In Group C, Pierce Marshall and Eric Foss carried the momentum of Friday’s B.R.M. Endurance Challenge overall race victory in the HSR Sebring Historics straight in to the HSR Classic 12 in pursuit of their first “HSR Classics” overall win. With the first two segments in the books, Marshall and Foss have co-driven the Matador Motorsports 2017 No. 02 Cadillac DPi to a more than one minute overall lead in Group C. While the lead margin looks somewhat comfortable on paper, the Matador team is being kept honest by Stuart Wiltshire who crossed the line first in Group C race two in his No. 10 Acura ARX-05 DPi.
