Short answer

Running at 35 °C, your body feels like about 40 °C, so dress as if it were 40 °C.

Rule of thumb: running makes you feel 5-8 °C warmer than the thermometer says. Dress for how you will feel once moving, not for the air temperature.

Running at 35 °C (95 °F): preventing heatstroke

At 35 °C the priority is not to overheat. Minimal clothing: a singlet or very light tee, thin-fabric shorts and, if you can, run at dawn or dusk rather than at midday.

Protect your head and eyes: a ventilated cap or visor, sunglasses and sweat-resistant sunscreen on face, neck and shoulders. A wet bandana on the back of your neck helps lower the sensation of heat.

Constant hydration and a much slower pace: at this temperature, holding your normal pace raises heart rate and heatstroke risk. Cut the distance, look for shade and, if you feel dizzy, nauseous or chilled, stop and cool down.

Recommended kit, item by item

Head and neck

Breathable cap or visor for the sun; nothing that insulates.

Torso

Breathable technical short-sleeve tee, or a singlet when it gets really hot. Avoid cotton: it holds sweat.

Legs

Technical shorts. Test them before a long run to rule out chafing.

Hands

No gloves needed.

Feet

Technical socks without thick seams: they dry fast and prevent blisters.

Sun

Heat and direct sun: UV-filter sunglasses and a sweat-resistant sunscreen. The most forgotten item, and the one that hurts most after kilometre 10.

Frequently asked questions

Is it safe to run at 35 °C?

With precautions, yes: slow down, avoid the middle of the day, carry water and wear light clothes. If humidity is high, it feels hotter and you should shorten the run.

What clothing helps prevent heatstroke?

Clothing that ventilates and dries fast: a singlet or very light short sleeve, technical fabrics and light colours. Avoid cotton and tight dark garments.

What if it rains at 35 °C?

A light, ventilated waterproof jacket, not a closed windbreaker. An ultralight rain jacket that fits in a pocket is usually enough.
