REVEL Big Bear Marathon
REVEL Big Bear Marathon race day weather
Cool start, warm finish ahead
Runners will face a cool start at 42°F, with temperatures rising to 72°F by the finish. Light winds from the ENE will provide a tailwind from miles 1-9 and 15-25, aiding pace during these stretches. Humidity is low at 37%, so hydration should be steady, especially as the temperature warms significantly in the valley. Runners should prepare for the heat in the latter miles, adjusting their pace accordingly.
This course drops 5,072 ft from start to finish, so we forecast it at 3 points, not just the start line. At 9:00/mi, you start at 42° and finish around 9:55 AM in 71°; the start line's forecast says 55° then.

About the REVEL Big Bear Marathon
REVEL Big Bear is a point-to-point downhill road race in the San Bernardino National Forest, starting near Sugarloaf Mountain outside Big Bear and finishing at Redlands Sports Park in Redlands, California. The marathon drops about 4,200 feet over 26.2 miles through Angelus Oaks and Mountain Home Village on paved roads and is USATF certified as a Boston Marathon qualifying course; the half marathon starts lower, at Forest Falls, with a comparable downhill grade. The race runs in November, though the full marathon was called off in both 2024 and 2025 for unsafe upper-course road conditions, with only the half marathon held those years. Source
