The IronRun is a challenging off-road running event. The wild 12k obstacle course is naturally carved out of 1000 acres of severe Northamptonshire woodland. You will run, crawl, jump, wade and swim through swamps, mud, hills, water and woods. It will test your physical and mental endurance skills to the max. This is adventure running at it’s purest.
