これが自転車に乗っている動画とは思えない。
この動画の中で、世界的なMTB（マウンテンバイク）サイクリストのダン・アサートンが、GoProを装着してイギリス・ウェールズの山中に作った急勾配のダウンヒルトレイル「レッドブル・ハードライン」を駆け下りた。アサートンは、岩だらけで気が密集した危険なコースを走り抜け、50フィート（約15メートル）の高さまでジャンプしている。
アサートンが自ら設計したコースとはいえ、MTBをあやつるアサートンも激しく息を切らせながらチャレンジしている。4分間の動画は息をつかせないくらいスリリングで、アサートンが無事ゴールした瞬間、見ている人もほっとしていることだろう。
