“Revolving nightmare” is how ultrarunner Will Goodge described his recent 2,387-mile run across Australia in 35 days. “I was having nightmares about what I was doing, and I just felt trapped,” Goodge told CNN Sports.

“It felt extremely claustrophobic. Even when I was out there, you’re in a great expanse – there couldn’t be more space around you. But for some reason, I felt very enclosed and the night seemed to drag out for a long time.”

“Hallucinations became an unpleasant and regular occurrence,” reported CNN as Goodge revealed, “kind of like you’re dreaming but awake at the same time,” Goodge’s Perth to Sydney is the equivalent of 2.5 marathons each day, said the Evening Standard newspaper in the UK.
