The mean (average) spead
Explanation:
Mean:
The professional will be much faster than the others and their timing will be an 'outlier'. It will introduce a bias to the upper end of the data giving the impression that the group as a whole is much faster than they really are.
Median:
Only affected slightly. It is the middle value once all the times are ranked in order
Mode:
Not affected at all as it is the most occurring single value or range
