The distance is too great for the attraction to make a difference
With air resistance, acceleration decreases. Without air resistance, acceleration remains the same throughout the fall ... the acceleration of gravity.
You completed 100.000 m in 11.800 second
you aced out the other runner by 0.001 seconds
time taken by other runner to finish = 11.800 + 0.001 = 11.801s
speed of other runner = 100/11.801 m/s
distance covered by him in 11.8 s = 100/11.801 × 11.8 = 99.992 m
you won by = 100 - 99.992 = 0.008 meter
