SPARTA, Ky. (AP) — Landon Cassill's latest double-duty travel itinerary left him needing a second wind.

Compared to this summer's grueling round-trip trek between the Sprint Cup Series race in Sonoma, California, and the Nationwide event at Road America in Elkhart Lake, Wisconsin, Saturday's journey from New Hampshire to Kentucky Speedway for the Nationwide race was a breeze.

After Saturday morning practice in Loudon, he drove to Boston to board a flight to Cincinnati. A pre-arranged police "taxi" from the airport cleared the way for Cassill to make it in time to qualify 22nd in the No. 01 Chevrolet for the 300-mile race.

He finished 29th and left right afterward to return in time for Sunday's Cup race in Loudon, where he'll start 30th in another Chevy. Despite the whirlwind travel, Cassill looked none the worse for wear.

"I'll get some good rest (for the Cup race)," said Cassill, 25, before heading to the garage.

It wasn't his first "road-eo" shuttling between both series.

"I've done all the races this year in terms of commutes, and Road America was probably one of the toughest ones," Cassill said. "That was crazy."

The upside for Cassill is that he won't have to do it anymore this season with Kentucky being the sixth and final stand-alone Nationwide race. He was the only driver pulling double duty this weekend, with many of his Cup cohorts focusing on the championship Chase race in New England.

Cassill entered Kentucky 11th in the Nationwide standings with three top-10s in 26 starts. His best series finish in three starts at the 1.5-mile oval was 11th in his June 2008 debut.

Veteran Jeff Green practiced in the car until Cassill arrived. Despite the mid-pack start, he improved to 12th by Lap 32 and stayed in the top 15.

Of course, getting there was half the challenge for Cassill, who has also learned how to pace himself. Tough as that California-to-Wisconsin round trip was, his hardest was a relatively short trip between a Cup race in Michigan and the road course venue at Mid-Ohio because the schedules overlapped.

"I really had to make a decision for every single session what I was skipping," Cassill said. "It's tough when you have to go back and forth multiple times."

This weekend wasn't much different, but at least Cassill can look forward to being in one place for the rest of the season.
