I recently received a training program from thefastplace.com, it worked great, ran a few PR's and great coaching advice...i was just curious to see if i was the only person who used a personal online "custom" coach??
I'd probably start with a member here, JasonFitz1 of strengthrunning.com. He's here quite a bit, consistently offers fantastic advice and seems to have a great amount of knowlege. And, if he gives you bad instruction, you know where to find him.
