At Active Fusion, we believe every child and young person deserves the opportunity to thrive, regardless of their background or circumstances. We work with schools, communities and partners across Doncaster and beyond to create opportunities for young people to be active, develop positive habits and access the support they need to reach their potential.
Through our campaigns, we bring people together to raise awareness, challenge inequalities and create lasting change. Join us in helping young people leave a positive footprint and shape a future full of possibility.
Lindsy James, founder of Active Fusion, created Limitless Within, a challenge taking place from 6th to 12th June 2027, bringing together an extraordinary test of endurance and a powerful message about mental wellbeing.
Lindsy will travel more than 1,055 kilometres from Loch Ness to London in just seven days, completing a 5km open water swim, 1,000km of cycling and a 50km ultra marathon.
The distance represents the approximately 2.3 million young people experiencing significant mental health difficulties, with every kilometre symbolising a young person and their story.
Inspired by Lindsy’s own experiences of overcoming challenges, Limitless Within aims to start conversations about mental health, resilience and the potential we all have to move beyond the limits we place on ourselves. The challenge will also bring businesses, communities and individuals together to raise awareness and support a brighter future for young people.


The Brotherhood: Rise Without Limits is Active Fusion’s Christmas Big Give Challenge for 2026, raising funds for a 12-week sport and mentoring programme supporting teenage boys facing poor mental health, disconnection and harmful online influences.
Through structured sport, trusted role models and guided discussions, the programme will help boys build mental resilience, develop a positive sense of identity and explore healthy masculinity. They will have the opportunity to talk openly about emotions, challenge harmful influences, build positive relationships and reconnect with school, their peers and their community.
At its heart, The Brotherhood is about giving teenage boys the support, guidance and belief they need to navigate challenges, recognise their potential and build a stronger, more hopeful future. Through the Christmas Big Give, we can help create opportunities for young people to grow, thrive and rise without limits.
Donate or host your fundraiser and make sure children and young people can access the benefits of physical activity and sport no matter where they live.
