Rob was the only one to complete the trek in the given time and Louise admitted she felt she had failed when the group discussed the challenge that evening.
Krishnan said: “I think we’ve got our heads around what’s going on now and what we’re doing. [Rob] completed it, the rest of us may not have done but we spent 10 hours out in that sun giving it everything.”
“I think Lou is struggling today,” Frankie observed to which Louise agreed: “I feel a bit… I feel like I’ve failed.”
Speaking to the camera away from the group, Louise welled up and confessed: “I knew this was going to be really, really hard but the distances and the heat are indescribable.
“I’ve never not finished a race and actually I couldn’t have done it. I could not have done it,” she continued.
“You think about yourself and what’s important, and what’s important is we’re out here to raise money and to help people.”
