A former British kitesurfing champion was brought out of a week-long coma after being seriously injured when he crashed into the ocean from a height of 65 feet while competing at the Red Bull King of the Air Competition in Cape Town, South Africa.

Lewis Crathern, 31, posted a message to his Facebook page from his hospital bed on Sunday and added a video Monday of him walking the hospital hallways. He is expected to make a full recovery.

"Overwhelmed by all the positivity in my crash at KOTA," Crathern wrote on Facebook. "For those interested I went for the first double mega loop…Late flip!! I’ll get it one day, thanks for all your kind messages they really keep me going!!"

Crathern, the freestyle British champion from 2005 to 2008, was attempting a massive kite loop at the start of the second semifinal, but his kite stalled, sending him into a horrific wipeout, according to Worthing Herald in the U.K. and Surfer Today.

The kitesurfer didn't suffer any brain damage, broken bones or internal injuries but had difficulty breathing, and when doctors found a lot of water in his lungs, they decided to put him into a medically induced coma, according to Surfer Today.

According to LiveLeak, Crathern was unconscious in the water and the event was suspended until he was successfully resuscitated. Here is his crash:

"From the lowest low to the highest high, although I couldn’t help but think of one of my best mates missing out on the final and ending up in the hospital," Aaron Hadlow posted on Facebook the day after winning the Red Bull King of the Air 2016, according to the Worthing Herald.

"At one point I was ready to walk away from my heat, but knowing Lew would be happy to see me on top when he comes around I managed to come out the blocks flying in the final, bringing his style and energy he had throughout the day with me."
