   • 1998 May 21, Mark Langton, “Attack of the singletrack”, in Daily News, Los Angeles, page S10:

     But there's a type of track that is the ultimate in the sensory cycling experience. It's called “singletrack” and only the most experienced need apply. Even then, tackling a one-lane mountain-bike trail is a daunting deed.

   • 2003 October 10, “Romero Canyon”, in Ventura County Star:

     For one trail, Romero Canyon sure can dish up a multicourse meal of riding conditions. A portion of steep fire road climbing, followed by some sweet, smooth singletrack, a side order of rock-garden challenges and, if you've got the stomach for it, a tree-canopied descent that will challenge even the best rider's technical skills.
