Pro Tips for September Running in LA

  • Dress for about 74°F (23°C), not the reading on your phone — you warm up 10–15°F within the first mile.
  • Hydrate before you leave and carry water or plan a route past fountains for anything over 30 minutes.
  • Light colors and a breathable singlet beat a technical tee once temps climb past 75°F (24°C).
  • Skip cotton in any season — it holds sweat and chills you. Choose moisture-wicking synthetics or merino.
