If you go beyond that, you are heavy, it is hot, it is high, the runway is contaminated or a combination of all. At DIA and ABQ it was not unusual to have a takeoff roll of :45 seconds or greater.

The question is.. why the abort after V1.

Everybody... look at were the skid marks begin... I think I saw them start near the end of the touchdown zone (less then 2,000 feet down the runway). SO, if it took me 41 seconds to get that far, I think I might abort because I am not getting enough thrust.

41 seconds must be from when they appied power to taxi onto the runway for takeoff. I don't think they were above V1....
