"Heat is a vibe. Embrace it or move to Iceland."
Heat needs respect, not avoidance. Slower pace, more water, smarter timing. The summer body is built when it's not summer-friendly.
- Run before 9:00 or after 19:00 in heatwaves.
- Drink 300–500 ml in the hour before.
- Slow down by 30s/km per 5 °C above 20 °C.
FAQ
What's a safe upper limit?
Above 30 °C with high humidity, shorten and slow. Above 35 °C, postpone unless you're heat-trained.
Salt or just water?
Anything over 90 minutes in heat: add electrolytes.
