I've joined a few step challenges on Garmin and some sync my info but others don't. Also, I can't figure out how to leave a challenge. If it's not syncing I might as well not be in the challenge.
Challenges that won't sync data-"Run 1000 miles by 1st January 2018"
-"Run 83.3 miles per Month"
-"Run the 19.2 miles Monday through Sunday"
The weekly challenge I join always syncs for some reason. SJ
