Lately I've been enjoying Bart Yasso's book My Life on the Run, detailing his many running adventures around the world. It even has a chapter on his bicycle tour across the United States riding over 100 miles per day. I had no idea he battled Lyme disease and addiction, which makes his stories even that much more inspirational... and he's a vegetarian to boot! The book has some training plans for all races and levels. I used his Yasso 800s method to improve my speed and it works.
