Runners ready to hit the pavement for the 52nd Scotiabank Calgary Marathon on Sunday will notice a few changes and additions to the route this year. And, anyone planning to be driving around Sunday morning will want to be up to speed on road closures.

One of the more noticeable route changes for runners is that corners will be marked with red chalk paint to ensure everyone knows when and where to turn.

New barricades have also been added in a few areas. For elite athletes, there will be additional lead cyclists and translators at the elite technical briefing for international runners.

Construction at the Flanders overpass will also mean minor changes to the marathon and 50K route for runners crossing east to west over Crowchild Trail.

The race is expected to attract 11,000 runners for the 50K marathon, 21.1K and 5K races. All money raised through the Scotiabank Charity Challenge goes to local charities.

Check the Calgary Marathon website for race day road closures, which will start at 6 a.m. Get more details on the route map here.
