DETAILED EPISODE SHOWNOTES: 

• We have detailed shownotes for all of our episodes. The shownotes are basically the podcast episode in written form, that you can read in 5-10 minutes.

Craig Alexander is a three-time Ironman World Champion and two-time Ironman 70.3 World Champion. In this episode we discuss the training and racing strategies Craig used during his career in detail. Craig also shares learnings from his post-racing coaching career on training considerations for age-group triathletes. 

HIGHLIGHTS AND KEY TOPICS: 

• An overview of Craig's training approach during his most successful years
• Key principles and example workouts in his swim, bike and run training
• How to race well in Kona

• Craig's team and coaches

• Common mistakes to avoid for age-group athletes
• Overrated and underrated products and concepts in triathlon

DETAILED EPISODE SHOWNOTES: 

• We have detailed shownotes for all of our episodes. The shownotes are basically the podcast episode in written form, that you can read in 5-10 minutes. They are not transcriptions, but they are also not just surface-level overviews. They provide detailed insights and timestamps for each episode, and are great especially for later review, after you've already listened to an episode. Naturally, as great as they are, they do not cover absolutely everything in as great detail as we can do in a 45-90 minute podcast episode.  
• The shownotes for today's episode can be found at www.scientifictriathlon.com/tts461/

LINKS AND RESOURCES: 

• Craig's website (Sansego) and Instagram
