All three models adjusted for your fitness, group, and conditions. Book Time weighted 50% in the final estimate.
Stay hydrated on the trail
For a hike this length, aim for 0.5L per hour of moving time. A reservoir pack keeps water accessible without stopping.
Browse hydration packs →Methodology: Moving time calculated as a weighted average of Naismith's Rule (1892), Tobler's hiking function (1993), and Book Time — each weighted 25%, 25%, and 50% respectively. Adjusted by fitness, group, and condition multipliers. Energy Miles use the Greenman formula (1 equivalent mile per 2,000 ft gain). Shenandoah difficulty = √(elevFt × 2 × distMi).
