You'll ruin your knees!
""...the truth that someday, you will go for your last run. But not today—today you got to run." - Matt Crownover (after Western States)
Your toughness is made up of equal parts persistence and experience. You don't so much outrun your opponents as outlast and outsmart them, and the toughest opponent of all is the one inside your head." - Joe Henderson
Gandalf the Grey
Running ... just keep running! Fancy a holiday running in the French Alps?
