Celebrating its 10th Annual Cycling Networking Tour, the Ziggurat Challenge will see around 70 riders from across the construction industry take on a fully supported four-day, 340-mile ride from Bilbao to Madrid, tackling an incredible 5,700 metres of climbing along the way.

We're proud to be taking part to raise vital funds for Action Medical Research, the leading UK-wide charity dedicated to saving and changing children's lives through medical research. For more than 70 years, the charity has been behind pioneering breakthroughs that have transformed childhood healthcare, including helping to beat polio in the UK, developing ultrasound in pregnancy, fighting meningitis and preventing stillbirths. Today, it continues to fund life-changing research into diseases and conditions affecting babies, children and young people.

Every year, thousands of children and families face serious medical conditions that urgently need better treatments and cures. With your support, Action Medical Research can continue funding pioneering research that gives children the best possible start in life and hope for a healthier future.

Every donation, large or small, will make a real difference. By sponsoring Herbsch-Kiere's Ziggurat 2026 Challenge, you'll be helping to fund groundbreaking medical research that could transform young lives for generations to come.

Thank you for taking the time to support our challenge and this incredible cause.
