Use long runs to rehearse fluids and fuel in warm conditions, but keep heat exposure progressive. Race week is not the time to test a new cooling, hydration, or fueling strategy.

  • Surface: Road.
  • Climate context: Avg highs ~ 31°C, lows ~ 24°C • Avg monthly precip ~ 71 mm • Avg wet days ~ 17 days.

Climate-specific adaptations (gear + fueling)

  • Warm/hot: start 1–3% slower, prioritize fluids + sodium, and practice cooling strategies.
  • Rain/wet roads: prioritize anti-chafe, socks, and traction; avoid brand-new shoes.
  • Fueling rule: practice carbs early and on schedule; do not “wait until you feel it.”
