Q&A #45 - Intensity unnecessary (?) for Ironman, warm-ups, lactate test timing, and adjusting a training week Is it really necessary to do any intensive training when preparing for an Ironman? Can you just do base miles?  When is the best time to get a lactate test?  How should you time your warm-up for an Olympic race, considering wave starts, transition area closing and so on?  How do you adjust a training week if you are prevented from doing one discipline (e.g. swimming) but could supplement with another (or two)?
