Skiing
Skiing was a sport. Joseph Serf, head of Serf Systems, died in a skiing accident in Val d'Isère in 2007, but as far as the public were concerned, he merely became reclusive. This was due to his PR, John Harrison, having him replaced by a hologram. (TV: The Man Who Never Was) Agreeing with Charley Pollard's comparison of Endarra to Bavaria, the Eighth Doctor suggested that he should teach C'rizz how to ski someday. (AUDIO: Scaredy Cat) The Twelfth Doctor took Clara Oswald to Isen VI to learn skiing, as she had volunteered to supervise a Coal Hill School ski trip with Danny Pink. (COMIC: Terrorformer) In Antarctica, Astrolabus used skis to flee from the Sixth Doctor. (COMIC: Voyager) Nate Simms once skied in the Snowy Mountains of Australia once over the course of a number of days. (PROSE: Invasion of the Cat-People)
