Race-morning weather
The start temperature is the middle half of past race mornings, and the high is the warmest hour while a 9:00-per-mile runner is on course, both from the race's own past editions near its usual date. 159 of the 194 races have at least three of them on file. Each race page has the full history and, closer to race day, the forecast.
How hilly
Climb per mile is the larger of the course's total climb and total descent, divided by its distance, from the race's course map, the same measure as our flat lists. Under 10 ft per mile is flat, under 20 ft per mile nearly flat and under 30 ft per mile gently rolling. 122 of the 194 courses are measured; the rest have no course map yet or one we are still checking.
