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

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/tts679/
