The California International Marathon is more than a running event, it’s a Sacramento institution, and the Sacramento Running Association prides itself on the positive impact CIM has on its host city. 

Since 2017, CIM has been a Gold Level Sustainability Certificatied race through the Council for Responsible Sport for producing a socially and environmentally responsible event. This multifaceted certification has only been completed by a handful of marathons across the nation.

CIM continues to implement sustainable practices and work with local and national partners to improve our processes. Our goal is to be recognized as the gold standard for sustainable events in our region. Please join us in these efforts.

Help CIM continue to be a Force for Good:


  • New or gently used clothing or shoes to Goodwill at the Expo 
  • Throw us your discarded clothes at the start line. Volunteers will be waiting
  • Make a donation to one of our partner charities when you register for your next race

THINK TWICE: Find the right space for your waste! 

  • Use the  “Sustainability Stations” at the Expo, Start Line, on Course, and at the Finish Line 
  • Recycling your nutrition wrappers in the Terracycle bins along the course
  • Use the water monster to refill water bottles and eliminate one-time use plastic bottles


  • Take FREE Regional Transit (RT) light rail or buses to or from the Expo or on race day
  • RT Passes are available online and at the Expo
  • Use the FREE SABA bike valet on the Capitol Mall on race day (Sunday)
