It's run day in Hamilton as the annual Around the Bay Road Race courses back for another lap.

The oldest meet of its kind in North America, the event is celebrating its 120th anniversary.

Around 13,000 runners, including Ontario Premier Kathleen Wynne, are set to take part in the race, which includes 30-km, 5-km and two relay events.

CBC Hamilton's Cory Ruf will be covering the event. To follow his Around the Bay tweets and pictures, keep an eye on the live blog below.

And if you're at the race, tweet your pictures, observations and best wishes for the runners to @cbchamilton, or use the #AroundtheBayCBC hashtag. We'll post many submissions to this page.
