Starfish... if you can find it in your budget... you seem like a prime candidate for hiring a coach.
I know for me, trying to figure out how to train for multiple events and then reading all the information out there... I was confused and overwhelmed. I just don't want to think about it that much... not mention, I'm scared that I'll make the wrong decision.
I have really enjoyed having a coach and just doing what he tells me to do. Now, I may not always do everything he tells me to do, but the guidence has been good.
I may have also found a local coach and I will probably switch over to him after my HIM, for my IM training.
Well, that's my input. Sorry I couldn't be more helpful...but I know for me getting a coach was the right thing.
