Running in the Heat: Pace, Timing & the Runner's Hydration

Your watch says 28°C and your training plan says 10K: what now? Running in high heat takes preparation — here's the summer runner's protocol, pace included, and the sugary « sports » drink trap.

• ⏰ Timing first: before 8am or after 8:30pm — running at noon in a heatwave doesn't toughen you, it exposes you to heat stroke. Above 25°C, the body needs 10-14 days to acclimatize: cut back first, build up after
• 🐢 The heat pace: add 20-40 sec/km from 25°C and forget the clock — heart rate rises 10-15 bpm at equal effort, that's physiology, not regression
• 💧 Before/during/after: 500ml of water + diluted INTI in the 2h before; sips every 15-20 min beyond 45 min of running; and post-run rehydration (1.5× the weight lost)
• 🔴 The « sports » drink trap: at 6-8g sugar/100ml they're justified on a marathon, not your 45-min jog — you drink back the calories you just burned. INTI = 0% sugar, taste that makes you drink without the calories
• 🥵 The runner's ginger bonus: heat-induced exercise nausea (common) = ginger's proven turf; and the ginger-turmeric anti-inflammatory supports summer-run recovery

Summer running that works: shifted hours, adapted pace (+20-40 sec/km), regular sips, and diluted INTI as a 0% sugar run drink. ⚠️ Chills mid-run, goosebumps, confusion, stopping sweating = imminent heat stroke: STOP immediately, shade, water — it's a life-threatening emergency in runners, every summer takes victims.
