Field notes
The calendar gives each run a start time, distance, location, and route-map link, then adds the sort of constraints runners need to plan around. One listing warns that there is no planned on-course aid and notes both sunset and a parking-gate closing time; another describes hourly starts over a 12-hour window. The site says runners are responsible for their own supplies, route knowledge, and safety.
