Distances span a wide range across those sports; you'll see 5K, 1 Mile, Half Marathon, 10K, and Marathon, along with other popular distances.
Weather on race day varies by time of year, so it lives where it’s accurate — each race page shows that race’s typical high, low, and rain chance from NOAA climate normals for its venue and date.
