...or articles as the case may be. Since we're in exam mode here, I thought I'd post a link to an interesting review article from Sportsci.org entitled "Intervals, Thresholds, and Long Slow Distance: the Role of Intensity and Duration in Endurance Training." Nothing new, but perhaps a good general review from a broad perspective - sometimes we get lost in the details. You can read/download the article from the main page (center panel, near the bottom), or you can read it here.
