Raising money for Basildon, Broomfield and Southend Hospital charities, helping them to enhance the patient experience, the #NHSGONUCLEAR 5k mud run is back for a second year. 

5k of outrageous obstacles, mountains of mud, zinging zip wires, and the world's only 20ft deathslide into a lake!

The event, held at Nuclear Races in Kelvedon Hatch, was inspired by personal trainer and Nuclear Races employee Laura Roberts whose son Oscar was treated for leukaemia at Broomfield Hospital.

“Oscar was diagnosed with acute lymphoblastic leukaemia in 2014 and Broomfield was our shared care hospital with Great Ormond Street. They were brilliant. He finished chemo two years ago but we’re still under Broomfield and go back every six months. I like to raise money for them because it’s a really good hospital.”

If like Laura you would like to say thank you to your local hospital for care received by yourself or a loved one, register for the event today.
