About the Portland Sea Dogs Mother's Day 5K

The course starts outside the Portland Expo building and winds through city streets before cutting through Deering Oaks park, then finishes on the field at Hadlock Field, crossing the warning track and ending near the home dugout on the infield. The Sea Dogs mascot leads the field out, and the top finishers throw out a ceremonial first pitch at a future game. Proceeds support breast cancer research.

Packet pickup is available at Hadlock Field the evening before the race and again the following morning, with race-morning pickup also offered. The organizers suggest picking up early to avoid lines on race day. A kids run goes off before the main event, free to enter.

Common Questions About the Portland Sea Dogs Mother's Day 5K

Will I finish last at the Portland Sea Dogs Mother's Day 5K?

Almost certainly not. Half the 5K field finished slower than 34:03, and the last recorded finisher came in around 1:05:40, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Portland Sea Dogs Mother's Day 5K a good first 5K?

With 1,147 finishers there are runners at every pace, so you are never out on your own. 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 Portland Sea Dogs Mother's Day 5K?

The 5K winner ran 15:12 while the median finisher took 34:03. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
