🇺🇸 No. 99 Robb Holland x 2023 Porsche GT3 Cup Robb takes on the mountain for the 8th time in his racing career competing for the Time Attack 1 trophy - some would say he knows this mountain. But as Robb would tell you, this climb always has a new challenge at every turn. This year is no different and we welcome that. #RobbHolland #PPIHC2025
