A British man in his thirties broke his thighbone while running close to the Seljalandsfoss waterfall in the south of Iceland, reports ruv.is.
The tourist was staying at a guesthouse and had gone alone in the moors above the waterfall last night when he fell.
Unable to contact help, he was forced to crawl for two hours until he was around 100 metres away from the national highway. There he was noticed by passersby who contacted the emergency services. He was then to taken to hospital in Reykjavík.
The man was only wearing a t-shirt and shorts when the accident happened, and was therefore very cold when he was found.
Hiking and running in the Icelandic wilderness can be risky as many trails are not regularly maintained and the ground can be treacherous.
