Worlds End Ultramarathon 50K
Calculated from 50 km alone — the organiser has not published an elevation profile. Read 2.5 as a floor, not a verdict.
What the course asks
DUV results for the 2026 edition (50km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
Typical conditions, May
Regional 2001-2020 average for May — NASA POWER, grid elevation 489 m. Not a forecast.

Course Notes
Loyalsock Trail, Loyalsock State Forest and Worlds End State Park. The routes are largely rugged, scenic-dense single-track trails with some fairly remote sections, several waterfalls and multiple vistas of the beautiful Endless Mountains.
