Big End at 1280mm

These were shot from more than 1/4 mile away from the starting line. The lens was a Canon 400mm, using a 1.6 crop sensor and a 2x extender (400mm x 1.6 x 2 = 1280mm).

Since it was late in the day the ISO was also high (above 1000 on all shots, 2500 on some of the shots before sunset).
