Catherine, Princess of Wales, recently completed the National Three Peaks Challenge, a grueling 24-hour endurance event covering the highest peaks in England, Scotland, and Wales. The Princess, who climbed with her brother, utilized an Apple Watch Series 11 to track her performance, including elevation, steps, and health metrics, while raising funds for The Royal Marsden Cancer Charity.
How the National Three Peaks Challenge Tests Physical Endurance
The National Three Peaks Challenge requires participants to summit Ben Nevis in Scotland, Scafell Pike in England, and Yr Wyddfa (Mount Snowdon) in Wales within a 24-hour window. According to event parameters, this involves approximately 37 kilometers (23 miles) of hiking and over 10,000 feet of total elevation gain. Beyond the physical climb, participants must navigate roughly 460 miles of transit between the sites, leaving minimal time for rest or sleep.
The Princess of Wales completed the challenge while wearing an Apple Watch Series 11 in an all-black aluminum finish. Given the distance, it is estimated the Princess would have tracked between 50,000 and 65,000 steps during the excursion.
What Role Did Technology Play in the Princess’s Climb?
The Princess of Wales utilized the Apple Watch Series 11 to monitor her progress in real-time. By initiating a hiking workout, the device provided live data points including precise GPS location, vertical elevation, and current pace. According to product specifications, the Series 11 features a 24-hour battery life, which is essential for an event of this duration.

Post-exertion, the watch allowed for the analysis of recovery metrics. The Training Load feature provides insights into how physical output impacts the body, while sleep-tracking sensors record duration and quality across REM, deep, and light sleep stages. The device also supports safety features, such as live location sharing, which allows designated family members to track a hiker’s movement remotely.
Why the Princess Supported The Royal Marsden Cancer Charity
The Princess of Wales framed her participation in the Three Peaks Challenge as a means to support The Royal Marsden Cancer Charity. In a statement posted to her social media, she noted that the journey through a cancer diagnosis requires more than just medical intervention.
“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 Princess stated. “The Royal Marsden is a place that holds great meaning for me.”

- Footwear Matters: The Princess opted for Scarpa walking shoes.
- Monitor Recovery: Use wearable sleep-tracking data to adjust intensity levels if completing multi-day physical challenges.
- Safety First: Utilize GPS-enabled cellular devices to share live location data with support teams when climbing in remote areas.
