Strava is challenging you to run a half marathon as fast as you can. Unlike a typical half marathon, tackle this Challenge from any location, at any time of day. Skip the travel and the pre-dawn alarm clock. Don't skip the chance to push yourself, and the pace.
Just pick a safe stretch of road or trail, record an activity that is at least 13.1 miles (21.1 km) long, and embrace the effort.
Athletes who complete this Challenge will receive a digital finishers badge in their Trophy Case.
You have to run 13.1 miles (21.1 km) in a single run, just like you do in a race.
Your position on the Leaderboard is based on the fastest average pace of any activities that meets (or exceeds) the Challenge goal requirement. The average pace is taken based on elapsed time and includes the entire duration of the qualifying activity (not just the fastest 13.1 mile section of your activity).
You will not show up on the Challenge Leaderboard unless you complete an activity over 13.1 miles (21.1 km).
To ensure you meet the Challenge goal, we recommend you run a small amount over 13.1 miles during your activity (about .5km / .3mi). This will give you a buffer in the event your activity distance is shortened after upload to Strava due to the cleanup of GPS irregularities. You can learn about how distance is calculated for our app by reading this Knowledge Base Article.
There is no time limit to complete the 13.1 miles (21.1 km).
The Challenge period starts and ends based on each runners local time zone.
Manual entries or treadmill runs will not count towards your Challenge effort.
All activities logged during the Challenge period must be uploaded to Strava no later than three days after the Challenge ends.
Have fun and be safe. Use common sense when it comes to traffic, weather, or other conditions while taking part in this Challenge.
