TRENCH™ CHALLENGE is the premiere obstacle course race in the western pacific region and the only qualifier to the OCR World Championships (Elite Division only). 

A long and short course is sprawled over the 250 acre property of the Guam International Raceway, offering variations in elevation and scenery changes from desert style terrain, mud pits, motocross dirt track and single canopy rainforest along cliff lines with spectacular views of the Pacific Ocean. With over 24 combinations of manmade and natural obstacles and an average temperature of 81 degrees fahrenheit and relative humidity varying between 60-94%, the climate alone can pose an obstacle for even the fittest athletes.

TRENCH™ CHALLENGE to date has raised over $20,000.00 for Special Olympics Guam, Guam Cancer Care, The Make A Wish Foundation, and other organizations.
