Walker Tracker is an online step tracking program designed to promote walking and physical activity. Healthy UC Davis introduced this program to the campus community in Winter Quarter 2019 as a 6-week pilot. While there was the option to complete the challenge individually or as a group of 4-6 team members, group participation was encouraged to promote social engagement. The program targets an achievement of 8,000 steps per individual daily, which can be achieved by taking active breaks from an office desk, lab or classroom. Generally, there was a lot of enthusiasm about this program amongst the UC Davis community. Participants reported an increase in moderate-level physical activity, and those participating in 150 minutes or more of vigorous-intensity activity reported higher motivation to participate in physical activity than baseline.
