You've never seen racing like this.  

Races can last from just a couple hours to elite races lasting over a week.  It is all trekking, biking, paddling, and orienteering basically non-stop.  The longest race I've covered was the "72 Hour Sea To Sea"race that takes place each March.

Day one of the 72 hour Sea to Sea Adventure Race. March 3rd 2016.

Howl at the Moon 18 hour Adventure Race that was held at Jonathan Dickinson State Park. September 19th 2015.
