The Blue Cross and Blue Shield Association's third annual National Walk at Lunch Day is today from 11 a.m. to 2 p.m. at Marion Square in downtown Charleston.

The public is encouraged to attend and walk for 30 minutes. The free event includes a walking course, health screenings, entertainment and giveaways.

Similar events are being held at the same time in Columbia, where more than 1,000 people attended a similar event last year, and Falls Park in Greenville.
