well, it appears as though I've hit my time threshold for a 10mi. flat TT (we have local practice every thursday night). The course usually involves a slight amount of wind but its beneficial during some portion of the race as its an out and back course. I have topped out at 23:30 and cannot seem to break that time barrier (unfortunately). I'm geared to the gills (disc, tri-spoke, helmet, shoe cover, skinsuit) so its not a technical issue (I can't buy more speed). Do any experienced TTer's here have any suggestions as to break through any time walls you've experienced? I figure the wind has some effect...my starts are not lightning fast, nor is my transition turn to home..so that might be a few seconds there, but I need some advice for upping my power output...my training isn't helping much in this regard...I weight about 160 if that matters.
