Your goal pace on a typical race morning

Built from the median race morning since 2000, averaged across the hours you’d be running. Where the weather costs time, each cell gives the adjusted finish time and the pace per mile to run instead. Six days out, the real forecast replaces it.

How I’d race a typical year

Run your goal pace. The weather will cost you a few seconds in the last 10K, not the first, so bank nothing early and take water at every station after mile 10.

Race week, start to finish: how I’d run the three-week taper, what to take in during the race, how much to slow down in heat and humidity, and what the four weeks after should look like.

Flying Pig Marathon weather history: every race morning since 2000

Every row in the table below is a measurement from the Cincinnati Lunken Airport weather station, taken nearest 6:30am (today’s first-wave start) and again three hours later. Start times have moved over the years, so treat 6:30am as a clock time, not always the gun. Across 26 race mornings:

  • A typical 6:30am reading is 54°F with a 49°F dew point, a combined score of 102.
  • The warmest was 2022: 67°F with a 62°F dew point at 6:30am, a score of 129.
  • The most humid was 2010, with a 64°F dew point.
  • The coldest was 2026, at 32°F.
  • On 13 of 26 race mornings the 6:30am score was above 100, enough to call for a pace adjustment. Three hours later, 14 of 26 were.
  • The weather changed the race itself in 2024 (red flag for heat) and 2023 (storms: shelter-in-place order mid-race).
  • The windiest start was 2004: N wind at 16 mph.
  • Rain fell in the first 5 hours on 8 of 26 race mornings (1 more saw only a trace). The most rain measured was 0.98 inches, in 2023.

Readings from the Cincinnati Lunken Airport ASOS weather station (NOAA/FAA, via the Iowa Environmental Mesonet), the observation nearest each hour. Scores above 100 call for a pace adjustment. Rain is the total the station measured in the 5 hours after 6:30am. Download every hour as a CSV.

How the score works

Add the air temperature to the dew point, both in Fahrenheit. That combined score is closer to what your body feels than the temperature alone, because dew point decides whether your sweat can evaporate, and evaporating sweat is how you shed heat at race pace. The bands below are the same ones my heat pace calculator uses, and that page has the full chart and the physiology behind it.

Combined score → how much to slow down
  • 100 or lessNo pace adjustment
  • 101 – 1100% to 0.5% slower
  • 111 – 1200.5% to 1% slower
  • 121 – 1301% to 2% slower
  • 131 – 1402% to 3% slower
  • 141 – 1503% to 4.5% slower
  • 151 – 1604.5% to 6% slower
  • 161 – 1706% to 8% slower
  • 171 – 1808% to 10% slower
  • Above 180Hard running is not recommended

The bands are a coach's rule of thumb, not a lab measurement. Treat each range as a starting point and let effort make the final call.
