Coming March 16, 2019. Remember to wear your green! The Blarney Blitz is a big celebration of St. Patrick’s Day held in the city of Peoria, in central Illinois. There’s a 5K run/walk on a flat course along the riverfront, followed by a party with live Irish music, food, and of course, green drinks at the local Irish pub! As they say, “come to race, stay for the party”!
