Commuting in hot weather

First, when the heat is extreme and your ride will be a long one, it might be safer to use some other kind of transportation. Otherwise...

Moisture-wicking cycling socks help keep your feet from getting too sweaty, or at least will dry out more quickly than thicker cotton socks.

For a short trip, you might be content to wear a t-shirt and shorts. For longer rides, consider the tips in my page on sun protection.

When it's really hot and dry, soak your clothes just before departing. If they dry out, soak them again partway through your trip.

If you're familiar with the area you will travel in, you can plan a route that lets you stop and rest in cool shaded places.

Consider bringing a cell phone. If your bike breaks down, stopping to repair it or walking may expose you to too much sun and heat. Summoning a ride could be safer.




When your ride will be short, you don't have to bring any water with you. Otherwise:

Drink beyond your thirst. Drink before, during, and after rides. As a crude guess, you could try to drink between 0.5 and 1 liter per hour.

If you weigh the same at the start and end of your ride, you replaced whatever water you lost due to perspiration and breathing. You could weigh yourself before and after a typical ride to see if you are losing water; if so, then drink more water on your next trip.

Many authorities seem to think that you should use no carbonated or caffeinated drinks for hydration. Plain water works better.

On a long trip, you might need sports drinks or food. I lack expertise in physiology, so I don't want to give more specific advice than that.

For longer trips, you could carry two insulated water bottles:
