About the Event

Embark on a unique urban-to-rural journey along a historic waterway at the London Lea Valley Ultra on Saturday, 21 March 2026. This point-to-point 50km (31-mile) ultra offers a truly distinctive experience, starting in Welwyn Garden City, Hertfordshire, and finishing in the vibrant heart of East London at Hackney Wick. The entirely flat route follows the beautiful and traffic-free Cole Green Way and Lea Valley Path, tracing the River Lea from tranquil countryside through parklands and into the dynamic urban landscape of the capital. With a 9:00 AM start and an 8-hour time limit, it's an accessible yet challenging early-season ultra, perfect for runners seeking a fast, scenic, and well-supported long-distance adventure without the mountains. Secure your spot for a memorable race that connects the English countryside with the iconic cityscape of London.
