All three sections of a triathlon are grueling both physically and psychologically. Swimming forces you to not only deal with your physical ability to cut the water, but it mentally challenges you to stay focused through the unpredictability of open water. Cycling, which is physically more challenging in terms of maximum heart rate, gives no physical break following the swim, and it requires intense mental attention as you must manipulate a machine at high rates of speed.

Running, the third and final stage, however, trumps both in its physiological and psychological demands. Runners tax their bodies like no other athlete, as evidence by the long wait periods between major races. No runner can compete at high distance levels week after week like a cyclist can. No runner can perform the multi-faceted workouts in repetitive fashion that a swimmer can.

Runners must be acutely aware of their situations. Injury prevention is critical when building a running base for a triathlon, as overuse problems stemming from too much volume too quickly or insufficient rest can destroy any person's triathlon season. As far as elite runners go, they spend roughly 25% less time training than their counterparts in swimming and cycling.

Psychologically, the run can mentally hinder any ill-prepared triathlete. As the final stage, the run not only pushes your fatigued body, but it also sternly challenges your mind. Your mentality is stressed from the moment you hit the water, so as you enter the last phase, your brain is tired. Training yourself psychologically, knowing how to handle your body, playing mental tricks to keep focused, understanding how to overcome your brain's desire to ease up, will provide you with great returns come race day.

Overall, be smart about your run training on both levels. Set reachable goals that will allow your body to make small, manageable strides. Along the way, pay attention to how you respond psychologically to the difficulties you face. Knowing how to handle your brain on race day may prove to be the difference for you.

Running, whether on roads, trails or tracks, represents a tough challenge, especially for beginners, so finding the shoe that not only suits your style and form but also properly fits your foot is your initial task when looking to maximize your running experience. Seasoned runners will tell you that an ill-fitting shoe causes continual damage, from small blisters and mild discomfort to serious sores and footfall problems. If you use the wrong shoes, you risk needless injury, as your form suffers, throwing off your symmetry and creating muscle and structural concerns.

To avoid these issues, follow the tips below to insure that the shoe itself fits well and will not, weeks down the line, cause irritation and injury.

When trying on a shoe...
• Make sure that the upper portion fits snuggly and securely on the top part of your foot. The part of the shoe that covers the top of the foot should not squeeze too tightly or cause any pain whatsoever. If it does, find a different pair, because this part of your foot will receive considerable pressure and stress while running.

• Check the shoe's toe box to see if you will have adequate room; you do not want your toes pressing tightly together or getting cramped. To test, press your thumb down between the tip of the shoe and your big toe; your thumb should fit comfortably in between. Anything tighter restricts the toes.

• Try adjusting the back of the shoe where your heel rests. Your heel should fit firmly in place and not slide up and down. If the heel moves, blisters and agitation will result.

• Evaluate the widest point on your foot. As all people have varying widths, find yours and make certain the shoe is not overly tight. If it is, it will disallow the rest of the shoe from flowing with the foot when running. While you do not want the shoe to slide on your foot, you also do not want it to choke your foot either.

Choose wisely and best of luck!
