Regarding CTL:
Right now mine is sitting right in the low to mid 50's. Based on the time I'm willing to devote to this sport (5-7 hours a week) I'm figuring my theoretical maximum would be around 65-70 depending if I did the old man training schedule (2 weeks on 1 week off) or the young man training schedule (3 weeks on 1 week off). And that gets depleted even further by sick days or "Dad, I need to get to a previously unscheduled basketball practice" days. So probably knock another 5 points off the top there. That does, at least partially, explain my lower level of fitness than a lot of racers. And I'm ok with that.
