Gnat,

I'm using CTS. (It was a Christmas present.) There are things I like and things I don't. I think individual satisfaction depends quite a bit on the coach to whom you are assigned. I switched coaches after the first 6 weeks because my first coach missed two of our weekly prearranged telephone calls in a row. (The stated reasons for missing the calls were lame, too.)

The CTS website has good videos to show you how to do the various drills and the online schedule is handy. It's nice to have someone analyze my Garmin data and to tweak my schedule as needed. I do like having a plan for each workout and I like that I don't have to come up with that plan!

I'm curious to see what sort of improvements I make. DH is doing Mark Allen online training for tris and he's very happy with that.
