Other changes besides an increasing workload can put us at greater risk of overtraining. For example, temperature extremes -- a heat wave or cold snap -- can present new challenges to which our bodies have to adapt, and trying to maintain our usual workload under such circumstances can lead to trouble. When we add new walking or jogging routes that take us over new terrain, for example, or when we change running or walking shoes or buy a new bike without giving our bodies time to adapt, our risk of injury and discouragement increases. Likewise, new stresses on the job or at home, when added to the stress of training, can increase the risk of overtraining.
