Compass Carter Osborne is delighted to announce the return of The Big 100 Cycle Challenge taking place on Thursday 10th of September 2026.

Historically, participants could choose from a 100km or 100 mile route, however we’re delighted to announce an all new 50km route launching in 2026 - making the event more accessible than ever.

The ride follows a carefully planned and fully guided route, with experienced road teams and medically trained support in place throughout, allowing riders to focus on enjoying the experience.

More than just a cycle, TB100 has grown into an engaged community event, with riders connecting through training, fundraising and a collective commitment to doing something positive together.

All funds raised support Spread a Smile, helping to bring joy to seriously ill children and their families. Through in-person and virtual visits and events, Spread a Smile’s entertainers – from magicians to musicians, artists, fairies and therapy dogs - enhance wellbeing and help young patients and their families cope with the pain and anxiety of serious illness and hospitalisation, developing bespoke relationships with each family and each health setting, so that we can offer the most impactful support.
