The focus of the Half Moon Bay International Marathon is to showcase the beauty of the Northern California coastline and our unique "Coastside" environment, sharing what we consider to be "Running Heaven" with athletes from around the world. To preserve and protect our beautiful habitat, we have built a world-class event that is sustainable for years to come by minimizing the impact as much as possible on our delicate eco-system. 

In our inaugural year of 2011 we attained the coveted Gold Certification from the Council for Responsible Sport, achieving the highest level of certification in recognition of our extraordinary efforts.

We are very proud of this achievement, and it reflects our investment, focus and a team of efforts led by our Chief Green Officer. We worked with the non-profit organization Athletes for a Fit Planet as consultants on our efforts to attain this success and we are grateful for their advice and guidance.

In 2012 we encouraged our athletes to make a difference by purchasing carbon offset "Green Tags", and Green Laces from the non-profit organization and many took advantage. A total of 71 Green Tags were purchased by HMBIM athletes. Each Tag offsets 300 lbs of CO2 so the total CO2 offset is 21,300 lbs of CO2 or 10.65 US tons. 13 pairs of Green Laces were also purchased.

FitPlanet-logo.jpg2011Gold_complex.jpgCRS is the recognized, non-profit organization dedicated to helping to Green athletic events through awareness, programs and certification.  To qualify for a Gold standard is no small feat, as we had to comply with standards set in five separate categories: Waste, Climate, Equipment & Materials, Community & Outreach, and Health Promotion. Click on the FitPlanet logo above to see the Sustainability Pledge the HMBIM is committed to. You can see the full list of standards at the CRS web site at

We strongly believe that if done right, we will not only preserve the beauty on our coast, but will leave it better than we found it by fostering a more eco-conscious community.  This is where you, the athlete comes in. We need your help to make this happen!  We will outline our entire Green plan in communications well before the event date, but it will include many things that you can do on race day to help, including:

  • BYOB!  Bring your own water bottle.  This helps greatly reduce the number of paper cups used out on the course. Each aid station along the course will feature a BYOB station where pitchers will be ready to refill your bottle! BYOB is strongly encouraged, however we will have cups with fluids at the aid stations if needed. 
  • Recycle!  Our goal is to have less than 1 lb of landfill waste per athlete.  To make this happen, we will provide recycling bins for bottles, cans, plastic and cardboard.  Please make use of them!
  • Composting! We aim to compost all food waste along with the food service products (plates, cups, utensils).
  • Carpool! If you have friends who are running the race, please share a ride to the start and from the finish!  

Thank you for joining us in the care and concern for our Coastside running environment! We look forward to seeing you out there on the course!
