Embrace the Sweat
Riding in the heat of summer sometimes means 'embracing the sweat'. But, there are ways to reduce your exposure to record-breaking heat. Cycling early or later in the day, stay well hydrated, and slowing your pace will help you keep cooler. Wear well-ventilated, wicking clothes in light colors, and bring a change of clothes when bike commuting. Acclimatizing to heat will also help your comfort and performance as you bike through the summer.
As always, be aware, alert, ride defensively and enjoy the pedal-powered breeze.
