The t4c also tracks your real-time Training Effect, a quick and accurate measurement of how hard your body is working at any given moment. By knowing your Training Effect, you'll enjoy a more intimate understanding of your body's workout "sweet spot," an essential tidbit if you want to achieve your targets without setting yourself back by under- or over-training. The Training Effect works intuitively: The watch first notes the info from your personal fitness profile, and then analyzes your physiological progress and translates the data into a simple one-to-five scale. For example, if you want to improve your aerobic fitness at a moderate tempo, you should exercise until your TE meter reads between 3.0 and 3.9, two to four times per week. To improve your aerobic condition more rapidly--but without the risk of over-training--you should push yourself harder once or twice per week, so your TE meter reads 4.0 to 4.9, with a few recovery sessions in the TE 1.0 to 2.0 range. The Training Effect is relative to each individual. While a novice runner might achieve a TE of 4.0 on a four-mile jog, a professional runner might have to complete an uphill marathon to get the same reading. In other words, both runners will have to exercise hard to achieve a TE of 4.0.

The Suunto t4c also offers interference-free digital ANT transmission, making it easy to pair your heart rate monitor with the included Suunto comfort belt. You can also use this secure connection to monitor your speed, distance, or cadence by pairing your Suunto t4c with an optional Suunto training pod. Training pods are small units that attach to such items as a running shoe or a bike to calculate your speed, distance, and even pedal revolutions per minute while you exercise. Pods are ideal for athletes who aren't satisfied with half-hearted training efforts, but really want to monitor their training routines down to the last detail. Finally, the t4c is equipped with an integrated training logbook that compiles your progress and personal stats. You can even conduct a more thorough analysis of your workouts by using the Suunto Training Manager Lite software.

About Suunto
Suunto was founded in 1936 by outdoors man and a keen orienteering enthusiast, Tuomas Vohlonen, who had long been bothered by a problem: the inaccuracy of traditional dry compasses and their lack of steady needle operation. Being an engineer with an inventive turn of mind, he discovered and patented the production method for a much steadier needle, better readings, and a new level of accuracy. By 1950 the company was exporting compasses to over 50 countries around the world, including Canada and the United States. In 1952, Helsinki was hosting the Olympic Games, and the torches carried to light the Olympic flame were Suunto products. The next step was improving the stability and accuracy of marine compasses. The first marine compass, the Suunto K-12, was launched onto the market in 1953. In 1957, Suunto started manufacturing hypsometers, which measure the height of trees.

In the 1960s, the compass range grew further and Suunto introduced its first diving compass--initiated by the divers themselves. A British sports diver attached a Suunto compass to his wrist and found that the device also worked underwater. Thanks to his feedback and initiatives, the new business category was found. Suunto's exports and business grew steadily and Suunto then focused on combining its strength in precision mechanics with new skills in electronics. Accuracy, reliability, and ruggedness have been Suunto's key values from the very beginning of the company history.

Today, Suunto is a leading designer and manufacturer of sports instruments for training, diving, mountaineering, hiking, skiing, sailing, and golf. True to its roots, Suunto is today the world's biggest compass manufacturer. Prized for their design, accuracy and dependability, Suunto sports instruments combine the aesthetics and functionality of watches with sport-specific computers that help athletes at all levels analyze and improve performance. Headquartered in Vantaa, Finland, Suunto employs more than 500 people worldwide and distributes its products to nearly 60 countries. The company is a subsidiary of Helsinki-based Amer Sports Corporation with the sister brands Wilson, Salomon, Atomic, Precor, and Mavic.
