Almost certainly not. Half the race field finished slower than 42:02, and the last recorded finisher came in around 1:05:47, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.
It is a small race (78 finishers), which is friendlier and less intimidating than a big-city event, though the field thins out. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first race, that spread matters more than the winner's time.
The race winner ran 20:01 while the median finisher took 42:02. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
