Hi guys,
I am a keen cyclist and can give you some advice on how to improve without going the whole way and employing a personal trainer. Sign up for Training Peaks year programme which is a web based system tracking all your metrics from nutrition to performance. Test yourself on Wattbike and find your functional threshold power output FTP in watts. ( pedal 20 minutes for your max output and take off 5% to get your FTP ). Go to Training Peaks and purchase a 3 month training plan based on your FTP devised by Hunter Allan, a world renowned guru in training with power. Inport this programme into your online calendar and voila you have your own plan based on wattage. The site even sends you e-mails with your next daily workout! Do it and you’ll never look back!
