You can post distances to your mission in 3 ways
1. Using the mobile app - Tap the "progress" tab at the bottom of the screen and enter your distance.
2. On the web at www.myvirtualmission.com. Log in and enter your distance just below the map on your mission page.
3. Via Fitbit, Strava, RunKeeper or Map My Run/Ride. Go to "My Connections" from the main menu.
Please note that the mission does need to be "launched" in order to post distances to it.
