The event begins at an elevation of over 9,600 feet on Guardsman Pass, immediately introducing runners to high mountain air and the unique challenges of altitude. The initial three miles follow a steep, winding descent through several tight switchbacks, demanding both caution and control to avoid burning out quads early and to navigate the sometimes tricky turns. This accelerated drop sets an aggressive tone and can invite runners to start faster than intended due to the aid of gravity.\n\nAt mi

Based on historical weather data for June, the expected race day conditions are as follows. Moderate temperatures between 14°C and 26°C are expected.

There is a low chance of rain (3%), so dry conditions are likely.
REVEL Big Cottonwood Marathon is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths. Trail surfaces are inherently slower than road courses due to uneven footing, technical sections, and often steeper gradients. Trail-specific shoes with good grip are recommended, and runners should expect a finish time 10-20% slower than their equivalent road marathon time.
