In addition to JR'S and Thor's comments I would add a specific answer to your question: Fluid or rigid? If you go with Thor's style then it is fluid, but if you go with JR's, it needs to be more rigid, to help mitigate the chance of injury.<br><br>
In other words, if you actually set down a plan, with really specific, quantifiable objectives (push 700 watts (!) for 30 minutes on the trainer), then you really need to follow a plan, and stick to it. But if you view the prep phase as merely a chance to ease back into training, go with how you feel and not worry too much about it.<br><br>
Reading JR's post again, I think that is a real good view. One can view the sole purpose of base training on the run is to be able to do speedwork without getting injured. A nice benefit is you get in good shape along the way. Similarly for strength training on the bike, it is for getting ready to push a big gear for the duration of your race. You need strength to do that.<br><br>
If you want some more specific answers, we need a little more about what you are training for, and when it (they) is (are).<br><br>
Since this prep phase is the first thing you are easing into at the start of what is likely a long season, the last thing you want to do is make it drudgery. Like Thor said, be consistent, do some training.<br><br>
