Q&A #40 - When to choose a road bike in a non-draft race, using half or full Ironmans in the lead-up to a big goal race, and making up calories after big days of training
Q&A #40 - When to choose a road bike in a non-draft race, using half or full Ironmans in the lead-up to a big goal race, and making up calories after big days of training How do you know if you should choose a road bike or a tri bike for very hilly races like Ironman 70.3 Nice? Can you use half and full Ironmans in the lead-up to an important goal race or are you better off just training? Should you make up all calories expended on a big day of training that same day, or can you make them up the following day?

Nitrate loading, marathons, and endurance sports science with prof. Andy Jones | EP#187
Professor Andy Jones is internationally recognized for his work in academia and applied sports science. He has authored more than 280 original research and review articles, worked with the two best marathoners in history (Eliud Kipchoge and Paula Radcliffe) and is perhaps best known for his pioneering work in the use of dietary nitrate (found in e.g. beetroot) and its impact on endurance performance. IN THIS EPISODE YOU'LL LEARN ABOUT: -Nitrate loading: what are the benefits and what is the proper protocol for it? -Can nitrate loading be done with normal beetroot juice or beetroots, or are specific supplements preferable? -Will we see the 2-hour marathon milestone broken soon, and what advances in running should take place for it to happen? -Running and endurance performance in large part comes down to three parameters: aerobic capacity (VO2max), economy, and lactate threshold. How should we train to improve these parameters? -The Critical Power concept and how it stacks up to Maximum Lactate Steady State SHOWNOTES: https://scientifictriathlon.com/tts187/ THAT TRIATHLON SHOW HOMEPAGE: www.thattriathlonshow.com SPONSORS: Precision Hydration - One-size doesn't fit all when it comes to hydration.
