The incredibly motivational Sophie Radcliffe is an endurance athlete, adventurer, blogger, mindset coach, entrepreneur, and keynote speaker. She is the only person in history to have climbed the highest mountains in the eight Alpine countries and cycled between them, climbing five times the height of Mount Everest in 32 days. She was awarded the Rising Star in Sport as one of the 100 most influential women in London, and is founder of the youth empowerment initiative TrailBlazers. Her aim is to champion ordinary people achieving extraordinary things.

Radcliffe had a life-changing moment in her mid-twenties when she gave up her job with a technology startup company to pursue her athletic dreams. Within seven years, she had cycled from London to Paris in 24 hours nine times, competed twice in Ironman Wales, took part in the 3 Peaks Cycle Challenge, and achieved a world-first expedition with the Alpine Coast to Coast by climbing the highest mountains in the eight Alpine countries and cycling between them in 32 days. She became a hugely influential speaker, motivating and inspiring others to challenge themselves to live life to the full.

Radcliffe regularly connects with her legions of followers and fans through Twitter, Facebook, and Instagram, posting pictures and videos of her healthy lifestyle. She also has a dedicated YouTube channel, Challenge Sophie, and an official website, challengesophie.com.
