Someone posted between-aerobars pov video of the first hour on IMMT bike course (almost to the turnaround St. Jovite). Could be a good tool for some athletes training indoors this winter for IMMT. It also could be a great illustrations of vagarity of drafting in Ironman races - some drafting didplayed in this video was intended, some resulted from ignorance, some was subconscious, and some was "forced" by density of riders.
