@bfrostieone I was completely prepared for the 70.3 distance. There was plenty of work done at 90 - 95% that prepared me for the steady state work at 80 - 85%. I did a couple 2 hr rides outside, but that was more for bike handling skills and getting mentally adjusted to variable terrain and wind conditions. If you have the time, I would do Sweet Spot Base I & II in place of the triathlon base. I think that style base just worked better at getting me to push the pedals harder for longer.
