Gordo Byrn is a former investment banker turned professional triathlete at a later stage in life without an endurance sports background. He podiumed at Ironman New Zealand and Ironman Canada, and also became Ultraman World Champion. Today, Gordo is a coach and a prolific writer, with a lot of great thoughts and perspectives on how to improve performance in triathlon and endurance sports, and even in life. 

HIGHLIGHTS AND KEY TOPICS: 

• The importance of high-volume training, mainly at low intensity, in Gordo’s training philosophy.
• Gordo’s comeback to endurance sports in his 50s after a long time out from consistent and focused triathlon or other endurance sports
• Why you should not do an Ironman within your first year of triathlon training
• The difference between adaptive and maladaptive training load, and how to make sure you stay on the adaptive side.
• The importance of lactate testing to establish your low-intensity training zones
• Practical tips for age-group athletes on how to apply more “elite” or professional training principles to their day to day life and constraints
• The main differences between professional Ironman training methods in the 2000s and today.

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.
