Core issue: I've considered that too, but I really feel like I've been putting a lot of time developing my core, so, for vanity sake, I probably will strike that out.
Knee issue: This one physically bothers me the least, but mentally is on my mind as I would hate to think that my knees are planning mutiny. I will indeed bring that up as a top concern with Curtis (fit specialist suggested elsewhere in the NorCal forum).
Back issue: That's great to hear. It would be nice to not feel that little tightening in the back when I climb.
Sorry, should have been more clear; it is a bike I've had for 2 years, as a replacement for an old bike stolen. It is a customized bike, but I don't think the fitting is quite right just yet as I've noticed more of these issues this year as I'm putting in more intensity in the training.
My concern is that I'm planning on doing a half ironman the second week of September, and don't want to do a fitting until after the first weekend of August (I have a full ironman), so I'm wondering if I should go ahead and do the fitting in that tight window, or should I just wait until after the half ironman is over.
My soap opera.
