Cascade Crest 100 Mile Endurance Run

Loop through the Cascade Mountains via the Pacific Crest Trail and forest roads. 23,000 ft of elevation gain through old-growth forest and alpine terrain.

Late August in the Cascades: 45–75°F. Pacific moisture means rain is possible at any time. Cool at altitude, warmer in valleys. Perfect late-summer conditions when dry.

22 aid stations; pacers allowed from mile 52. Drop bags at multiple locations.

Rain in the Cascades can make the PCT sections dangerously slippery and adds significant time to sections where athletes expected faster travel — calorie plans based on time estimates become outdated quickly.
