不太確定 inline alpine skating 怎麼翻譯，根據 wiki:
Alpine owes its existence to skiing, because many skiers commonly practiced
it in the summer months during its origins, as it helped them to train despite
the lack of snow. Skaters complete a course marked by gates while descending
at high speeds. Its basic movements are therefore similar to those of downhill
skiing and many athletes regularly practice both modalities.

應該只需要一個長坡、一雙競速直排輪、護具，就可以練習。
有板友玩過嗎？北部地區有什麼地方可以練習？
有沒有人有興趣一起研究？ (有的話站內信給我～)
