My good friend Matt Fitzgerald is back with a new book The 80/20 Triathlon.  This training principal is a winning formula for most any endurance sport and I highly recommend that all of my listeners pay attention to this episode.  It works for OCR too!  Once you understand how important it is to partition your training with a high percentage of aerobic conditioning and when and how to apply intensity you'll start to see progress in all aspects of your program. Ya gotta go slow to get fast!
