Pro Tips for July Running in Seattle

  • Dress for about 66°F (19°C), not the reading on your phone — you warm up 10–15°F within the first mile.
  • This is close to ideal running weather. A short or long sleeve tech shirt covers most runs.
  • Bring a light layer you can tie around your waist if the wind picks up.
  • Skip cotton in any season — it holds sweat and chills you. Choose moisture-wicking synthetics or merino.
