Similar to liking a Facebook post or favoriting a tweet, Kudos are a quick thumbs-up you can give to your fellow athletes to congratulate them on a noteworthy activity, achievement, post, badge, or challenge milestone. From your feed, you can see how many Kudos have already been given and add your own. You can also give Kudos directly from the activity page or athlete post. Once you give kudos the icon will turn orange. To see the list of athletes who have previously given kudos, click on the number next to the Kudos icon. There is currently no way to remove Kudos once they have been given. You can manage your kudos notification preferences in your settings.
