Q&A #81 - "Race pace" or Z2-training for Ironman; FTP-tests vs. race-specific fixed heart rate tests For slower Ironman athletes, target race pace and Z2 are pretty much the same.  Is there any benefit in training (in particular running) at race pace if it realistically is just a slow shuffle?  What are the pros and cons of a classic FTP-test vs. riding at a fixed (race-specific) heart rate (or power) and measuring how power (or heart rate) progresses for that fixed value?   LINKS AND RESOURCES: That Triathlon Show website  Coaching Training Plans   SPONSORS: Precision Hydration - One-size doesn't fit all when it comes to hydration.
