- Wear several layers of clothing while training. As you warm up, you can remove clothing and then put it back on while resting or as the day turns cool.
- Look for clothing that allows your skin to breathe and sweat to evaporate.
- Stick with synthetic fabrics that dry quickly. Cotton absorbs sweat and can give you a chill.
- In the rain or cold, wear a waterproof outer layer with secure closures around your neck and wrists to keep you dry.
- While training, wear the clothing and equipment (including waist pack or backpack) you will use on the event, in order to get used to it.
