The course runs along the water at Seal Point Park, with bay breezes that are noticeable from the start. The route stays close to the shoreline, so you get open views across the water for most of it. The terrain is gentle, and the feel is more neighborhood gathering than competitive event, with a kids dash happening alongside the main race.

Going by the 2025 results, this is a decent-sized field, and the spread of finish times is wide, so this is a mostly recreational race rather than one for club runners.

Almost certainly not. Half the 5K field finished slower than 52:16, and the last recorded finisher came in around 1:21:05, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.
A field of 310 is big enough that you will have company at your pace without feeling lost in a crowd. 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 18:13 while the median finisher took 52:16. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
