“Using CORE to monitor the core body temperatures of the Bora-hansgrohe riders has been a game-changer. The use of CORE sensors has a major influence in developing specific warm-up procedures before races, optimal fluid intake, and in our choice of clothing.”

2023 Western States Endurance Run Winner

“I used CORE in the build up to the Western States 100 because heat training is essential for success in that race. CORE took the guessing out and I trained more specifically than ever, allowing me to improve my heat acclimation and also plan a specific cooling strategy. It was a game changer.”

Cycling

We have seen virtually all the World Tour teams using CORE at some point to support their performance needs, with some purchasing the technology out of pocket. However, CORE is proud to be officially supporting the following 8 teams in the professional men’s and women’s peloton for the 2024 season.

“I’d never raced in Kona before. People thought I couldn’t win without experience in the island’s legendary heat and humidity, but I was extremely well prepared because I had used the CORE sensor to simulate the core body temperatures I would experience during the race. I adapted to those elevated core temps as if I’d always trained and raced in Kona.”
