CORE, the Swiss-based real-time core body temperature sensor specialist, is signalling a new direction with leadership changes.
The recent appointment of Ross McGraw as VP and Head of CORE (with experience at Hammerhead, Paramount, and VICE), alongside advisor Cees De Witte, formerly of Giro, Spyder, New Balance, ATOMIC, and Bell Sports, is seen as a strategic move to reach a broader audience.
Guided by company founder Wulf Glatz, these new appointments… ‘reflect CORE’s commitment to growth and expansion, building on its reputation for enhancing performance through heat training and cooling strategies.’
“We live in a world where global temperatures continue to rise,” said CORE’s new appointment Ross McGraw.
“For athletes that train to perform in race conditions, core body temperature is fast becoming a key metric to properly prepare for and perform at any race. I believe that continued product innovation will enable CORE technology used by the best athletes in the world to be used by everyone to keep them safe and help them perform better.”
Launched in 2020, CORE delivers real-time core body temperature monitoring technology. Citing an association with numerous Olympic gold medals and athletic success including at the IRONMAN World Championship, Tour de France, and the men’s and women’s hour record, the technology is seen to be key in delivering performance advantages.
Founder, Wulf Glatz is a mechanical engineer by education (Ph.D. ETH Zurich). Glatz founded CORE’s parent company Greenteg to use heat flux technology in photonics, building efficiency and other areas. He launched CORE after witnessing the dramatic pictures of Sara True suffering a heat stroke during the 2019 IRONMAN Frankfurt.
Wulf Glatz said “Ross McGraw’s background as a business executive who has worked with growing companies and brands in the consumer sector including NIKE, VICE, Intel, Paramount, and Hammerhead combined with his personal experience as a runner, and former pro triathlete make him the perfect leader for the next stage or CORE’s evolution.”
New advisor at CORE, Cees De Witte, added that “When virtually every top endurance athlete is using the same technology without being paid to do so, it’s a clear sign they see value in what CORE has built. In a world of sports tech wearables, this is the missing metric towards unlocking human potential.”
The CORE sensor is a non-invasive wearable sensor that measures thermal energy transfer and provides core body temperature and thermal measurements. The discrete sensor clips to a heart rate monitor strap during sport and delivers live data directly to a bike computer or smart watch.
CORE enables athletes to see how temperature rises with intensity and to trace the impact it has on power. Using the device, athletes can train hot to race cool, adapting the body to internal and external heat. Pacing and cooling strategies can also be used to help sustain performance for longer.
The CORE sensor is UCI legal, and with it riders are able to view their own real-time core body temperature data. For post ride analysis, rider data can be synchronized with the CORE App and other training applications.
CORE officially supplies Soudal Quick-Step, INEOS Grenadiers, Movistar, Lidl Trek, BORA Hansgrohe, and Astana.
Filippo Ganna, Dan Bigham and Ellen van Dijk all relied on the CORE sensor and expertise for their UCI Hour Record rides. At the Tokyo Olympics, Richard Carapaz, Anna Kiesenhofer, Tom Pidcock and a number of elite track cyclists trained with the CORE sensor.
