Topics covered:
- Why rest and recovery are NOT the same thing
- The 80/20 rule that elite endurance athletes swear by
- How your gym sessions are secretly adding to your riding load
- Why masters cyclists (40+) need smarter spacing — not less riding
- The one non-negotiable rest day every rider needs
Whether you’re riding 3 days or 6, this episode will change how you think about your training week.

- Researcher study on 12 female cyclists showed that a 122% increase in training load correlated with elevated resting cortisol and reduced recovery scores across somatic stress subscales — PubMed URL: https://pubmed.ncbi.nlm.nih.gov/17101532/ PubMed

- A study comparing masters and younger cyclists across consecutive HIIT sessions found that while physiological recovery markers were similar, perceptual fatigue and soreness were significantly higher in masters athletes — PMC URL: https://pmc.ncbi.nlm.nih.gov/articles/PMC8822894/ PubMed Central
- Australian study using nine veteran cyclists (avg. age 45) vs. nine younger cyclists (avg. age 24) across three consecutive high-intensity time trials found that masters athletes reported higher perceived fatigue and slower subjective recovery, even when objective power output was matched — Sports Performance Bulletin URL: https://www.sportsperformancebulletin.com/training/masters/endurance-and-aging-can-you-turn-negatives-into-positives Sports Performance Bulletin
