The Old Mutual Soweto Marathon App is a great way to track runners during the Marathon.
It also offers great features such as training guides and the OM Live Digital Radio featuring podcasts on the ins and outs of this year's edition of this iconic race.
If you want to track a runner, search by using either both their first name and surname, or their race number.
You will be sent notifications as your athlete's timing chip passes certain key mats on the route.
You can also use the App to post photos to the photo gallery and share your race day updates on Instagram, Facebook and Twitter.
Be sure also to use App’s interactive map on race day to find route guides, check points and water points.
For race runners, the App offers brilliant training guides to help you get to the finish line, whether you're running the 10km, 21km or 42km race.
The App can be downloaded for free from the iTunes App Store or Google Play.
