So my question is: Is my bike fit crap so that I am using only certain muscles which are then completely overused? (it was feeling like the anterior chain and inner rotational muscles were completely done, my posterior muscles must have been underused when I can get uphill upright?) I am not using my strong posterior chain?
To get some things out of the way:
- I did not overpace. Last Ironman was 258W NP, and in February I did a 6.5h ride at 256W even prior to starting any interval training (although on a road bike with an undoutably perfect fit)
- I did a bike fit, 3 actually. The last one I am using now is from the same fitter that made the perfect fit on the road bike, but I never liked this tri bike fit. I did never have this much saddle setback
- I thought I was used to the position. I do all my indoor training on a tri bike, and some outdoor rides. But of course you are never as long in aero position as in a race (especially with traffic outdoors), also in 70.3s I didnt really notice the issue.
