Hunter Allen says that if you want to improve something then you must be able to measure it. We measure data such as Power (Watts), Cadence (RPM) & Heart Rate (BPM) plus more information. The data is stored by a company called Trainingpeaks. Trainingpeaks is a company headquartered in Colorado and each athlete receives a FREE basic account from Trainingpeaks. You can record information about your bicycle rides, swims, runs, nutrition, indoor cycling and much more. Sign up for your free account and start improving now.
