NEWTON, Iowa — For the most part, IndyCar drivers enjoy racing at Iowa Speedway.
That doesn't mean Sunday's race is going to be easy.
The temperatures expected to reach the low 90s by the time the green flag drops. It's also the last of five straight races without a break, and few tracks in the IndyCar Series are as physically demanding as Iowa's steep-banked, .875-mile oval.
Though Iowa's "bullring" setup is great for the fans, it's easy to see why many drivers think the smallest oval on the IndyCar circuit is also the most draining one this season.
"It's probably the toughest (track), especially after five weeks. It is what it is. That's why we prepare ourselves for that," Tony Kanaan said. "Myself physically, I tried to be ready because I knew it was going to be a long stretch. But you can tell. Everybody's getting tired."
Iowa isn't exact the ideal place for a weary race team.
It's so small that drivers are turning four times about every 17 seconds — at speeds of up to 185 mph. That, combined with some of the steepest banking in IndyCar and the lack of a true straightaway, puts tremendous physical pressure on the drivers.
Brad Goldberg, an engineer for the No. 83 Chip Ganassi Racing car driven by Charlie Kimball, said that at Iowa the G-force is roughly five times a driver's body weight laterally and twice that vertically at its peak.
