The Marlborough Lions Club Round The Lake 5K has been held every year since at least 2025. That is as far back as RunSignup's records for this race go, so it may well be older.

Almost certainly not. Half the 5K field finished slower than 31:49, and the last recorded finisher came in around 55:23, 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 (97 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 5K, that spread matters more than the winner's time.
The 5K winner ran 17:07 while the median finisher took 31:49. That spread points to a mixed field, with a competitive front and a big recreational middle.
