I have worked with a few individuals in the past. I am starting to work with a coach on a regular basis in a few weeks. Of course the TT threshold test is what a few cycling training books I have also read recomend. Everyone is different though and that may change when I start working with my new coach...

My current plan is focused on the cyclist training bible and that is what he recomends for testing. That will all change when I start training with a regular trainer though...
