The sought after Kudos on activity tracking and sharing app Strava is how friends on the platform celebrate and congratulate each other's achievements.
Strava "Mules" or 'Surrogates' have emerged to help runners obtain the recognition without actually doing the activity. Instead, a '"Mule" will be sent out with a paying customer's Strava account logged into their phone and paid to run in their place.
The customer gets the result they wanted — to share with their friends on Strava — and the 'Surrogate' is paid for their time. Entrepreneurship!
