Timex Ironman Run Trainer 2.0 GPS Technologie Strapless GPS heart rate monitor watch T5K745 Data Sheet

You can set up zones for heart rate, speed, pace, and cadence. To do this, input upper and lower limits for 

these workout data, and the watch will sound an alert when you are outside of this range to prompt you to 

change your workout behavior to get back in zone. 

Zones help you train at a specific intensity, which can help you target your workouts for a particular physical 

quality. 

You can set up one set of heart rate, speed, pace, and cadence zones for the chronograph, and one set of 

zones for each of the six intervals. By combining multiple zone settings with the interval timer, you can design 

workouts to help you get precisely the results you want.

Pace is the number of minutes it takes you to run one mile or kilometer. 

It is important to know your pace both when you are training and during a race. While training, you can set 

a pace slightly higher than your race pace to build speed. When you are racing, you can adjust your pace to 

make up for slow miles or avoid burnout resulting from starting out too fast. 

This chart shows the pace to set to achieve your desired race time.

Your fitness goals determine what your optimal heart rate zone should be; the heart rate zone you want to 

target for burning fat is different from the zone you should target for endurance training. 
Use the charts below to estimate your optimal heart rate zone based on your gender, age, and goals. Working 

out at the Aerobic Base level of intensity (in the middle of the charts) will help you burn fat and build aerobic 

endurance. However, you can also use the watch to tailor your target heart rate zone for more specific values 

appropriate to your current fitness level and your fitness goals.
noTe: Values on these charts are based on a percentage of your maximum heart rate (MHR). Consult your

doctor before beginning an exercise program and to confirm the heart rate zone that is right for you.
