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. 
• The shownotes for today's episode can be found at https://scientifictriathlon.com/tts689/

If you enjoyed this episode, I think you'll love the following related episodes:

• Gordo Byrn on optimising Ironman training, the importance of volume and low intensity training, and practical age-group training - already a 2026 classic for That Triathlon Show, Gordo is a fantastic coach, athlete, thinker and communicator. This is one not to miss!
• Ironman World Champion Solveig Løvseth on her race day strategy in Kona, her training block at altitude, heat training and more! - Less relevant for age-groupers perhaps, but from a pure triathlon and Ironman performance perspective, it’s fantastic to hear exactly what the current Kona Champion did leading up to her great victory. 
• Craig Alexander – Three-time Ironman World Champion - Crowie is one of the legends of the sport, and provides a fantastic perspective on how triathlon training and Ironman training specifically has evolved over the last two decades.
