My advice would be, if you developed or picked a plan then commit to it and be 100% confident in it. If you aren't sure about it before you even start then its not the right plan for you, that anxiety will only grow as you do your training. I believe for an athlete to succeed they must have confidence in three things, without all three the chances for success are greatly reduced:
- Themselves
- The Plan
- The Coach
There are a lot of resources out there - too many. I have worked with athletes that want to try every new thing they read on some random website or in an article in Triathlete Magazine. My job as their coach is to keep them focused on the task at hand and have them commit to their training rather than spend time reading blogs or articles with lots of conflicting "advice".
With that said, the best book on long course triathlon training is Going Long by Gordo Bryn. I have followed Gordo's career as an athlete and coach for many years. I spent a week with him at a training camp last summer and I agree with his coaching philosophy. I recommend his book to any 70.3 or IM athlete looking for more knowledge. But, though reading a book can be helpful, trying to put the concepts into practice for yourself for an event that is less than 5 months away is another thing altogether.
I had suggested earlier that you consider taking advantage of the Kansas 70.3 training plan I have put together for KC Multisport members, I continue to encourage you to do so. If we work together to achieve your goals the anxiety will fade and your questions about what, how much, when, how often, how hard etc. will start to be answered.
