Open every month, our mileage training series is there when you need an extra challenge. Whether you start the Challenge on September 1st or join in the last week, set yourself a distance goal and and make it happen!

To keep you motivated along the way, there are four five milestone achievement badges to be earned. They start at 40 km and go all the way up to 200 km.

WIll this be your biggest month of the year? Push yourself this September by increasing the distance of your runs and/or adding an extra day of training to your weekly calendar.
