Kate Middleton’s fitness tracker recorded over 50,000 steps on the Three Peaks Challenge - here’s the one she chose

On descending Yr Wyddfa (Mount Snowdon) after completing the Three Peaks Challenge, Catherine, Princess of Wales, was met by Prince William, their three children, and her parents. She completed the hike with her brother. It was a moment captured by photographers and recently shared on the couple's social media pages.

The Three Peaks Challenge is a 24-hour event where participants must climb the three highest points in England (Scafell Pike), Scotland (Ben Nevis), and Wales (Snowdon), travelling between the mountains. The time limit makes it a real physical and mental task, as participants are often left with limited time to sleep and rest between climbs.

On her wrist, Kate wore the Apple Watch Series 11, the brand's latest. Featuring a 24-hour battery life, accurate and insightful workout data, and strong GPS with the cellular model, it's a reliable option for the Princess of Wales, who would have logged at least 50,000 steps on the Challenge.

In total, the distance is 37 kilometres (23 miles) with more than 10,000 feet of climbing, and about 460 miles of driving between the mountains. Based on average stride length, height, and pace, the future Queen would have tracked 50,000 to 65,000 steps over just one day and night. Luckily, she also had some good Scarpa walking shoes on.

The Apple Watch Series 11 is one of the best fitness trackers today. After starting a Hiking workout, the watch displays live workout data, so Kate would have been able to see how many steps she was taking, the distance she was covering, elevation, speed, and her precise location at every step along the way.

When the climb was over, she would have seen an overview of each hike, revealing the total distance, step count, average speed, and elevation, and she would have been able to see how these efforts impacted her body via the Training Load feature.

At night, Kate would have been able to see how well she slept (if only for a few hours) while wearing the watch, with sensors recording how long she slept for, her various stages of sleep (REM, deep, and light) and how well she slept, rounded up into a Sleep Score.

The watch can also play back music through exercise headphones, make and receive phone calls and texts, and take pictures remotely, all of which come in handy when you're taking on such an adventure.

The Apple Watch Series 11 also has new sharing features, so should she have wanted to, the Princess of Wales could have sent her live location from the watch to family members, who could have tracked her along the way.

Lightweight and ultra-thin, this Apple Watch also has the brightest screen to date, with a new scratch-resistant layer over the top to protect against bumps and bashes while walking or hiking.

Many hikers complete the Three Peaks Challenge for charity, and Kate was no different. Earlier this week, she posted to Instagram from atop one of the climbs, revealing that she was raising money for The Royal Marsden Cancer Charity, an effort you can still donate to today.

She said: "Cancer doesn’t just affect the body. It changes how you think and feel and profoundly affects every aspect of life. I know this personally, and that the journey through and beyond treatment requires more than medicine alone.

"I have taken on the National Three Peaks Challenge, not simply as a physical endeavour but as a chance to explore life beyond diagnosis and to give something back. The Royal Marsden is a place that holds great meaning for me and whose care and expertise are life changing for so many people."
