Mountain Biking

Trail Running

Run dirt, roots, and ridgelines where the roads end.

Run dirt, roots, and ridgelines where the roads end.

Which is right for you?

Choose Mountain Biking if…

  • You want the lung-burning climb and the white-knuckle plunge back down.
  • Letting the bike move beneath you on singletrack is the rush you are after.
  • You are fine walking sections locals float until your eyes look further ahead.

Choose Trail Running if…

  • You want the outdoors and the run combined, roots and ridgelines underfoot.
  • A clean kind of tired with your head quiet on an empty ridge is the draw.
  • You are fine walking the steep parts and reading roots three feet ahead.

Before you commit

Mountain Biking

  • A twitchy bike on a trail faster than you would rattle your nerves.
  • The unglamorous, honest grind up the climb is effort you would rather skip.
  • Crashes, roots, and rock gardens sound like injury risk, not fun to you.

Trail Running

  • Tripping and rolling an ankle on roots and rocks would put you off fast.
  • Running slower and harder than on road would frustrate you, not free you.
  • You want flat, predictable pavement, not terrain that drops your eyes down.
