Eight runners stood out among the thousands of participants of The Jakarta Marathon 2015. Bayu, Tyas and six members of the Chubby Indo Runners Team were not only participants, but ran the full and half marathon while carrying the #BeliYangBaik mission.

The Chubby team wore t-shirts with images of endangered animals such as tigers, orangutans, elephants and sharks, with the beliyangbaik.org logo on the chest, and RSPO, FSC, MSC and ASC labels on the back. The use of this special t-shirt is a form of support for WWF Indonesia's #BeliYangBaik campaign. Through this action, Tim Chubby and WWF Indonesia invite the public to participate in the #BeliYangBaik campaign and start a more environmentally friendly lifestyle.

Thousands of runners from various countries participated in the 2015 Jakarta Marathon. The event, supported by the Ministry of Tourism of the Republic of Indonesia, took place on Sunday morning, October 25, 2015.

After crossing the finish line, Team Chubby and Earth Hour Depok volunteers took action to wear masks and invited people around the National Monument to take pictures with masks and upload them on social media. The action was carried out as a form of sympathy for the people who are experiencing the negative effects of the ongoing haze, especially in Sumatra and Kalimantan.
