About
Join us for the Erie Half and 5k! The Hometown Race Series features half marathons and 5k distance events in outlying communities outside the Denver and Boulder metro areas. LOOK UP! At the Erie event, we often see the early morning skies with dotted with delightfully colorful hot-air balloons. Whatever distance you're ready to tackle, we'll be there with you to celebrate at the finish line! This is one of the few 5k events where FINISHER MEDALS are awarded to each participant. Go home with proof of your pride and show off that bling!
Save Erie Half & 5k to your season and RunCalendar reminds you the morning entries open and before they close. Free on iPhone, no account needed.
