The Princess of Wales showed off her stamina by throwing off her jacket and trying her hand at a gruelling polar training technique - but admitted she needed to do some extra training.
Kate was visiting Landau Forte College in Derby today to meet Captain Preet Chandi, who recently returned from a polar trek across the Antarctic.
The princess was a patron of the expedition and the pair joined together at the school, where Preet, who is from Derby, made a speech about her experience.
During the engagement, where Kate donned her Veja white trainers, Preet told of how she trained for her trek by strapping two huge tyres to her waist and pulling them along as she walked.
And not one to shy away from a sporty moment, Kate tried out the training method, with college students seemingly impressed with her efforts.
She removed her jacket before taking part and told them: "'I definitely need to do some training."
It came after Kate and Preet embraced in a huge hug when they met at the college earlier today with the princess wearing stylish navy trousers and a cream blazer from High Street retailer Zara costing just £69.
Preet made history in January when she completed the longest-ever recorded solo and unsupported expedition to the South Pole.
During her inspiring and gruelling trip, which lasted for 70 days and 16 hours, she crossed Antarctica in direction of the South Pole, walking 922 miles through temperatures as low as -30°C and wind speeds of 60mph.
To complete the expedition, she skied for 13 to 15 hours a day, pulling a sledge weighing 120kg.
Captain Chandi completed the challenge while on a period of leave from her Army role, having joined the Army Reserves at the age of 19 and the regular Army at 27.
She is now based in Buckinghamshire, working as a physiotherapist at a regional rehabilitation unit, helping injured soldiers with training and rehabilitation.
Dubbed "Polar Preet", she fell short of completing her target of going coast to coast, around 100 miles (160km) from where she was picked up.
But speaking at the time, the 33-year-old, from Derby, said: "Mentally, it was tough knowing I didn’t have enough time to make the crossing, but the expedition was about pushing my boundaries and inspiring others to do the same, so how could I not continue?
"I'm disappointed I ran out of time to make the crossing of Antarctica, but I did everything I could. I didn’t take a day off and pushed as hard as possible every day.
"I'm proud that I kept going when it was tough and I thought I couldn’t do any more."
