Temperature management during training is an important aspect that few athletes have discovered. New Ironman Triathlon World Record holder Jan Frodeno shows that it can give you the edge. The Cosinuss One is on sale now for 30% off in celebration of Frodeno's Ironman world record.

German triathlon athlete Jan Frodeno just demolished the world-record time for the Ironman distance in the competition in Roth, Germany on Sunday. Frodeno beat the 5 year old record time 7:41:33 set by Andreas Raelert by 6 minutes. He swam 3.86km, cycled 180km and ran 42.195km in the mind-boggling time of 7 hours, 35 minutes and 39 seconds.

Just last week, I met the co-founder of a German start-up called Cosinuss. The company makes an in-ear heart rate monitor that also measures the body temperature. Dr. Johannes Kreuzer told me that Jan Frodeno uses the Cosinuss One during training mainly to monitor his body temperature. Frodeno knows his current heart rate without measuring, but not the body temperature.

The so called "Cardiac Shift" happens when the bloodstream uses more energy for the body's cooling system. As a result, the heart rate increases but not the performance. With heart rate and body temperature an athlete can devise his optimum temperature management to increase performance.

Cosinuss One

The Cosinuss One wearable replaces the hated heart rate monitor chest strap. The lightweight device is compatible with a variety of smartwatches, smartphones and bike computers to display and record both heart rate and body temperature via Bluetooth.

In celebration of Jan Frodeno's record-setting victory in Roth, Cosinuss sells the Cosinuss One with a reduced price of 99 Euro (50 Euro discount over regular price, offer expires after 100 units sold) in company's online shop.
