Will Power started on pole position and led for about a third of the race, but took a spin on lap 40, which cost him several positions. Two laps from the end of the 85 lap race, Scott Dixon in the #9 Target Chip Ganassi passed Mike Conway and went on to win, with Ryan Hunter-Reay finishing second, and  Simon Pagenaud third. Hope you like the photos.

Decided to cover the start of the race from the top of the track above the spectator area so could capture the cars as they raced up the hill into Turn 2. Here’s a couple of shots from the start, which includes the mid-field collision between Ryan Briscoe in the #8 NTT Data Chip Ganassi Racing and Sebastien Bourdais in the #11 KVSH Racing (Canon 5D Mark III, Canon 70-200mm f/2.8L IS II with 1.4x extender III, 98mm, f/16, 1/1000, ISO 100)

After the race start, walked down the outside of the track to Turn 2 to get shots of the cars speeding through this uphill right-hander. Here’s, top qualifier Will Power in the #12 Team Penske leading Scott Dixon in the #9 Target Chip Ganassi Racing through this corner  (Canon 5D Mark III, Canon 70-200mm f/2.8L IS II with 1.4x extender III, 280mm, f/5.6, 1/1000, ISO 100)

Continued my walk down the hill to get shots of the cars speeding up the Turn 1 to 2 hill, with the GoPro Pavillon and Sonoma hills in the background (Canon 5D Mark III, Canon 50mm f/1.2L, f/11, 1/1000, ISO 100)
