Dale Earnhardt Jr. Uses 1-Word To Describe Kyle Larson's Effort

Sunday's result at the Coca-Cola 600 wasn't the one Kyle Larson imagined when he set out to complete the famed "double" over the weekend. But one of NASCAR's all-time greats is still impressed with the 32-year-old Hendrick Motorsports driver and his pursuit of history.

Larson's crash last night ended a disappointing day for Larson who wrecked in both the Indianapolis 500 and the Coca-Cola as he attempted to run both races in the same 24 hours.

Afterwards, Larson admitted to NBC Sports that it was a huge challenge and that yesterday might've been his last try at it. Telling the outlet:

"The Double is just a tough undertaking. The window of time is too tight. ... So I don't really think it's worth it. But I would love to run the Indy 500 again. Just doing the Double I think is just logistically too tough."

Dale Earnhardt Jr., who watched Larson's Sunday closely, still applauded Larson for what he tried to do. Calling it a "Herculean" effort.

"Talked about this on the 600 post race @SportsonPrime," Dale Jr. said. "What we don't see are the meet n greets, photo shoots, team meetings, travel, and more photo shoots, media requests... his plate is already full with those things in NASCAR and to add THE Indy 500!! It's a Herculean undertaking in May times 10. Unreal. "
