St. Patrick’s Day 5K Races Greater Boston 2025
Updated August 16th
The St. Patrick’s Day 5K races for 2025 are a ways off but it’s never to early to plan!
I’ll make updates for St. Pat’s 2025 as races post dates, times and details.
Please let me know if I missed your favorite race. If you are a race director, I will be happy to add your race also.
In 2025, March 17th falls on a Monday, so you can run a race on Saturday March 15th and on Sunday March 16th if you like. Who knows, there may even be a race on Monday March 17th.
And as you will see in this directory, the fun begins the week or two before, so you can run a St. Patrick’s Day themed 5K road race two weekends in a row or twice in a weekend if you want!
To register for any of these races, click the race title or the registration information link. The race title link usually has additional race details you need such as specific location, course information, awards, refreshments and if there are kids races available.
This directory is brought to you by the My First 5K finisher’s medal. Most of these races have medal for the top overall and age-group finishers, but may not have a finisher’s medal for everyone. Click a My First 5K image or HERE to check out the First 5K medal.
