For those of us who don’t want to take a 2nd mortgage to buy a power meter, Coach Fred Matheny tells us ways to determine cycling intensity and performance potential that don’t require gadgets. All it takes is applying some simple equations and simpler math. Coach Fred has personally tested all the formulas for accuracy in his own riding, and compared the calculated results with power meter readings.
