Races in the sweet spot
Upcoming Michigan races in the best-weather months.
How this is measured: every race on Find The Run carries 10 years of weather history for its exact location and calendar date. These monthly figures average that data across all 480 upcoming race days in Michigan — real race-day conditions in the US, not city-wide monthly normals. Daily lows land around sunrise, so the low end of each range is close to typical start-line temperature.
