'As cold as hard tyres in winter testing...'

Charles Leclerc lives in sunny and warm Monte Carlo which perhaps adds to the glacial challenge of undergoing a session of cryotherapy.

F1 drivers and athletes use the -120 degree Celsius cold compression chamber as a biting two-minute post-exercise recovery procedure that helps relax overworked muscles.

Leclerc posted on Instagram a picture taken during his most recent icy session with the caption, "It's cold".

One Lewis Hamilton was quick to respond, asking the Ferrari driver: "How cold?"

Leclerc offered his Mercedes rival the perfect reply:

"@lewishamilton as cold as the hard tyres in Barcelona winter testing 🥶"

Darn, that is cold!

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
