Author Jim Gourley
It's very possible you've never heard of Jim, but you might have read his articles in Triathlete Magazine, Inside Triathlon, or elsewhere.  He's definitely smarter than me and he's probably smarter than you.  He graduated from the United States Air Force Academy with a degree in Aeronautical Engineering.   
His new book, Faster: Demystifying the Science of Triathlon Speed, covers ways to pick up free speed that aren't training based.
In this episode we discuss:


How to gain free speed by your choice of tires
How important is your bike's weight?
Does weight matter in your choice of racing flat?
Is a treadmill faster or slower than road running, and why?  

Jim's book covers all these topics and more.  It's definitely worth a read. It's published by Velo Press.
