I recently got back into cycling after a 6-year hiatus. Previously, I had only trained for triathlons. After blowing out my knee, I can no longer run, but want to get back into cycling and start doing some road races. I feel like training for road races is quite different than training for triathlons. I'm not sure exactly where to start in my training. For the past couple months, I have been riding 4-6 times a week, but often feel like I have no plan in riding besides just pedaling and going. I have been keeping track of my distance and time, but know this "training plan" (if you can even call it that!) has no structure.

I was thinking of purchasing a training book (like The Cyclist's Training Bible by Joe Friel), or searching for training schedules online. I have also contemplated paying for coaching, but would prefer to not spend that kind of money if I don't have to. I know I need to mix some interval training, hill training, and long endurance rides, but am not sure on the best way to plan a training schedule. I want to improve my endurance, strength, and ability on the bike, and ultimately prepare for road races. Does anyone have any helpful advice or guidance on this?

Any help is much appreciated! Thanks!
