Luton and Dunstable Hospital’s Cardiology department was presented with a cheque for £1235 from three friends who took on an endurance challenge.
Cousins Kris Orr, 30, of Westhill, and Leon Brightman, 30, of Buckingham, took on the 26 mile obstacle event with their friend Scott Sage, in memory of their grandad, Derrick Orr.
They wanted to raise money for the department that treated their grandad on many occasions before he passed away in 2005.
Leon said: “We completed 26 miles in two days with obstacles, it was by far physically the hardest thing I have ever done.
“However, it was a good personal achievement and more importantly a great opportunity to raise money for a worthy cause in memory of my grandad.
“The money raised will go towards buying more heart monitors, we were told about how important these devices are to the patients and we were told how they work and monitor patients heart rates and rhythms.
“We explained what fundraising we did to Jack Welstead, one of the fundraising officers at the hospital, and he thanked us for our efforts and said how much the hospital appreciates what we have done.”
