"Go out and have fun," Andretti Autosport engineer Craig Hampson relayed to Kurt Busch mid-morning at the Indianapolis Motor Speedway.

Indeed, the Nevada native heeded the advice on the 2.5-mile oval during a special refresher program arranged in conjunction with his schedule that will get more hectic during May. Jacques Villeneuve, the 1995 Indianapolis 500 winner, was the other driver on the track going through a refresher course.

Busch, 35, will attempt to become the fourth driver to attempt the "double" -- competing in the 98th Indianapolis 500 and the evening stock car race in Concord, N.C., on May 25. He won the latter in 2010. John Andretti, Robby Gordon and Tony Stewart have each done it, with Stewart -- co-owner of Busch's No. 41 Sprint Cup car at Stewart Haas Racing -- becoming the first in 2001 to complete all 1,000 miles.

"This attempt is something serious," said Busch, who is scheduled to join other Indy 500 rookies May 5 at the Speedway for additional laps. "It's an amazing challenge."

Busch was off to a quick start learning the Honda-powered No. 26 Suretone car, with a stiff headwind entering Turn 1 of the iconic oval, recording a best lap of 219.991 mph. ABC analyst and former Indy car driver Scott Goodyear said such wind direction was more beneficial than the alternative, which makes the car "feel like it's floating." "(Drivers) can handle a tailwind in Turn 3 better," he added.

Because he tested last May on the oval last year in an Andretti Autosport car, Busch was required to complete the formal refresher program. In addition to demonstrating car control, placement and consistent driving pattern, the program consists of 25 laps that constitute the second and third phases of the Rookie Orientation Program at speed intervals based on track and weather conditions.

“I think we’re going to be strong in the race and I think we’ve showed that the past couple of years,” said Verizon IndyCar Series driver James Hinchcliffe, who made reconnaissance laps with Busch in a passenger vehicle. “He has more professional races under his belt than the rest of the field combined with as many races as NASCAR runs and I’m sure he’s going to adapt pretty quickly.”
