Lesley Paterson is a professional mountain biker, 3-time world champion in off-road triathlon, an Ironman® triathlon champion, endurance coach, and foul-mouthed Scots lassie.

Banned from the team when puberty struck, she took up cross-country running and triathlon and was soon winning national titles and competing internationally. Lesley founded Braveheart Coaching to train and inspire endurance athletes to compete with passion, toughness, and an unwavering “Braveheart” spirit in overcoming obstacles. Paterson is a trained actress, a screenwriter, and personal trainer to Hollywood actors.
