To better understand city runners and find opportunities for the design, I interviewed 5 people and ran three miles with the running group. Here is what I found:

Running through a city allow people to appreciate local neighborhoods, beautiful parks, and popular landmarks, but also deliver challenges, such as crime, traffic, and uneven surface conditions.

City runners sometimes feel uncomfortable running outdoor and hesitate to try out new running routes because of a lack of safe, convenient, and personalized routes.

• Helps runners to find routes based on personal preferences
  

• Allows runners to share routes with the running community
  

• Allows runners to explore and learn more about the city
  

• Allows runners to track their running performance
  

• For social features, users preferred the use of running groups over running partners.
  

• Runners did not want to take out their phones during the run and expressed a desire for expanded audio cues.
  

• Users expressed interests in learning more about their neighborhood and the city's history through running.
  

• Injury is a very common thing among runners, and the users find the "Highlights" of the routes very helpful.
  

• Concern about trust issue with group leaders.
  

• Suggest to include information to support first-time runner.
