About the Grand Slamrock

The course is flat and USATF certified, finishing inside a minor league baseball stadium. You cross the line on the actual field, and the scoreboard is running, so you can watch yourself come in on the big screen while the announcer calls your name. The St. Patrick's Day timing gives the whole morning a celebratory feel without being chaotic.

Parking is described as convenient to the stadium. After you finish, there is beer at the post-race gathering. Strollers are welcome on the course, though dogs are not.

Finish-Time Stats

Going by the 2026 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.

Common Questions About the Grand Slamrock

Will I finish last at the Grand Slamrock?

Almost certainly not. Half the 5K field finished slower than 35:35, and the last recorded finisher came in around 1:15:16, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Grand Slamrock a good first 5K?

A field of 627 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.

How competitive is the Grand Slamrock?

The 5K winner ran 17:29 while the median finisher took 35:35. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
