Jack Bristol Lake Waramaug 50km Ultra Marathon
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

Typical conditions, April
Regional 2001-2020 average for April — NASA POWER, grid elevation 149 m. Not a forecast.
