A capacity grid of 56 entries are set for next weekend’s Sahlen’s Six Hours of The Glen, the third leg of the IMSA Michelin Endurance Cup and the halfway point for the WeatherTech SportsCar Championship.
The entry list, released during 24 Hours of Le Mans festivities on Wednesday, features 11 GTP cars, 13 LMP2s, 11 GTD Pro entries and a class-high 21 GTD cars.
Watkins Glen will mark the first WeatherTech Championship race since March’s Mobil 1 Twelve Hours of Sebring where all four classes will be back in action.

Tom Blomqvist, who is listed in the No. 31 Action Express Racing Cadillac V-Series.R, will not race, per a Cadillac spokesperson.
Proton Competition is the only other team that could utilize a three-driver GTP roster, with two TBDs currently listed alongside full-season driver Gianmaria Bruni.
LMP2, which mandates three-driver squads, features no major changes since Sebring, other than the previously announced reshuffled lineup for DragonSpeed, which will see the debut of Nico Varrone and return of Eric Lux to the team.
Additionally, Scott Huffaker has replaced Laurents Hoerr in the No. 20 MDK by High Class Racing Oreca 07 Gibson as the team’s third driver.
