These down-to-earth, hard-working  Aussie brothers from Melbourne, are spiritually driven, love a sense of community, and share a drive for constantly challenging themselves to grow, learn and inspire. Their determination and grit has resulted in them being the first brothers ever to run across Australia from Perth to Melbourne (3,400km) in 2024, a testament to their hard work, persistence, self-belief and continuous improvement.

Lachlan (23 years) and Stefan Lamble (26 years), also known as the “Lambros Army” are elite endurance athletes and content creators known for their dedication to conquer physical feats and raise awareness for cancer research. After the loss of their grandmother to cancer, the brothers made it their mission to raise funds and inspire others to support the fight against cancer. To date, they have raised over $240,000 for cancer research and have become symbols of resilience, determination, and hope for a cancer-free world.

Having previously made history in 2024 in their trek across Australia, the boys next challenge  is a  world record attempt to become the fastest brothers to run the entire length of the UK from John o’ Groats in the North of Scotland to Land’s End at the southern tip of England in July 2025.   To break the current world record they must run 1420 kilometres in less than 30 days (47.33 kms daily).   For this challenge, the boys will be fundraising for both the Australian Cancer Research Foundation and Cancer Research UK, the largest independent cancer charity in the world.  The fundraising will be split between both charities, bringing cancer research in Australia and the United Kingdom together and raise much needed funds.

Lachlan and Stefan have built a tremendous social media platform of over 700,000 followers across IG, YouTube, and TikTok through not only taking their followers on their inspiring challenges and training, but also showing their zest for life , positive mindset, and philanthropy.

When the boys aren’t busy training and working on their next challenge, they enjoy spending quality time with family and friends, and are very passionate about sport particularly AFL football.

The brothers are also public speakers, motivating high school students about their run across Australia, learning lessons (i.e. perseverance, goals setting, healthy habits, mindset, etc)  and community impact.  Additionally, they coach individuals online to reach peak performance and achieve their athletic goals.
