Still not enough info. The race is legally a tie if the times are within a certain (I think a millisecond) interval, and with runners this similar in ability, the probability that nobody wins is non-zero.

The randomness in the air molecules are enough to case minor variation in finish timings. I think I should add that the observer can see the finish line with an accuracy of one Planck length and that observation uses a mysterious method which avoids Heisenburgs uncertainty principle. That should make the question well-defined 😆
