Marathumb is a lifestyle app developed by Saucony for Android devices. This free app offers a unique challenge to users, encouraging them to move their feet more than their feed.

The app allows users to track their scrolling distance and monitor their step count. By checking their stats, users can see if they are moving more with their feet and earn rewards from Saucony.

The Marathumb Challenge lasts for 6 weeks, starting on Monday, January 22. At the end of each week, participants who have completed the challenge are eligible for rewards. Users can check in daily to monitor their activity, view their stats, receive Marathumb Motivation, and share their progress with friends.
