About the Castle Ridge Shamrock Shuffle 5K

The course runs from the Castle on the Lake, a venue on the water in Centralia, and the race is organized around raising money for a local family who lost someone. St. Patrick's Day attire is encouraged, and age-group awards are handed out for a wide spread of divisions, from young kids through seniors.

Packet pickup and late registration both happen the morning of the race at the Castle Ridge Restaurant, before the start. Everything is handled on-site, so there is no separate pre-race trip required.

Common Questions About the Castle Ridge Shamrock Shuffle 5K

Will I finish last at the Castle Ridge Shamrock Shuffle 5K?

Almost certainly not. Half the 3.1 Miles field finished slower than 32:03, and the last recorded finisher came in around 1:01:56, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Castle Ridge Shamrock Shuffle 5K a good first 3.1 Miles?

It is a small race (151 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 3.1 Miles, that spread matters more than the winner's time.

How competitive is the Castle Ridge Shamrock Shuffle 5K?

The 3.1 Miles winner ran 17:19 while the median finisher took 32:03. That spread points to a mixed field, with a competitive front and a big recreational middle.
