Korosho Marathon is the product of the effort that the Government is making through the Cashewnut Board of Tanzania (CBT) to promote the development of Cashew production, processing, and marketing. It was established in March 2022 with the theme of encouraging local consumption and use of cashew products and by-products like jam, juice, cashew milk, wine, Ethanol, Cashewnut Shell Liquid (CNSL), and Apple meat that will automatically trigger the increase of local processing and have multiplier effects in the cashew business and economy of the country.  

 Korosho Marathon is aiming at raising funds to support small cashewnut processing groups in Tanzania,
especially for those areas (regions) with high processing capacities. It is expected that forty-five percent (45%) of the collected revenue from this Marathon will assist small processors to access shelling machines, packaging machines, and storage facilities.
