Trainer Road is a subscription-based training program that I have been subscribing to for about 8 weeks. I have had some FTP gains using it and it is convenient and straight forward to follow. As a subscriber, I have 3 x 1 month free trials to give away to friends etc. Let me know if you are interested. I need an email address so they can send you the free trial link. I don't get any rewards for giving away the trials. You will need a turbo trainer, power meter and smartphone/device to run the Trainer Road app. Each training plan runs for 8 weeks so I imagine this is giving you half a training plan as a taster.
