Dave Blair is an mountain biker, outdoors enthusiast, and writer who lives in Edinburgh, Scotland. Constantly exploring his country on foot or on bike, he knows many of the best (and worst) places for mountain biking and for short mini-adventures.
As someone who always loved reading cycling travelogues, it made sense for him to write about some of his own adventures in "Tyred Out".
