You have 3....count 'em 3... days left to get your St. Patrick's Day 10K/5K application in before the deadline. After this Thursday, you can still register, but you'll be paying $15 for the race and you will not get a shirt. So...it behooves you to get your application in the mail today.
(BTW -- if you don't get it in the mail before Saturday, don't bother -- according to the application, you'll have to sign up day of race if your application is mailed after 3/8).
The St. Patrick's Day race is an annual tradition that offers a 10K run and a 5K run/walk.
And, if you participated in the Erie Runner's Club's Turkey Trot & the First Day 5-Miler -- the St. Patrick's Day race is the final race in the winter "triple crown" series. Those who complete all three races are eligible to receive a really nice backpack (I've seen it...it's cool).
