Exclusive AMA: Distance vs Time, Goal Setting, & Half Mara Taper

·29 min·1 clip

Joel Tobin-White says speed workouts should stay distance-based because everyone races the same 21.1 kilometers or 42 kilometers.

1. The Run Smarter Podcast episode is an ask-me-anything session focused on distance versus time, goal setting, and tapering for half marathon and marathon training. 2. Brodie hosts the episode, identifies himself as an online physiotherapist working with runners worldwide, and frames the show around evidence-based running guidance. 3. The episode asks whether runners should use distance or time as the goal for long runs, how to set realistic race goals, and how a half-marathon taper differs from a marathon taper. 4. Kimmy asks about a slow runner doing a marathon long run of 32 kilometers that could take over four hours and whether time or distance should govern the session. 5. Brodie compares that question with Joel Tobin-White’s answer about speed workouts, where Joel said to keep the distance fixed because everyone races the same 21.1 kilometers or 42 kilometers. 6. Brodie says the long-run situation is different from speed intervals because 32 kilometers can become four to four and a half hours, which changes the training cost. 7. He cites coaches and experts who commonly point to 20 to 22 miles, or 32 to 35 kilometers, as a typical marathon long-run range. 8. He adds that if that long run goes beyond three to three and a half hours, it may be better to stop at the time cap than force the full distance. 9. Brodie describes diminishing returns and says a very long session can require a week, two weeks, or even three weeks of recovery. 10. He recommends, if needed, spreading the target distance across a 24-hour period so the runner still reaches the prescribed kilometers without one excessive session. 11. For Karen’s goal-setting question, Brodie says to write down current race stats such as the fastest 1K, 5K, 10K, half marathon, and full marathon times from the last six months. 12. He also suggests writing down how much improvement has happened over time, using a five-minute drop from 50 minutes to 45 minutes in the 10K as an example. 13. Brodie says race timing matters because a goal becomes more realistic when the athlete knows whether the race is in two months, five months, six months, or 12 months. 14. He recommends setting the goal first and then choosing a race that fits the target, instead of locking into a race and forcing the goal afterward. 15. Brodie outlines A, B, and C goals, with the C goal just above the athlete’s current best, the A goal ambitious but still achievable, and the B goal in between. 16. He adds five goal-setting features: clarity, challenge, commitment, feedback, and complexity. 17. Craig’s question shifts the episode to tapering, and Brodie defines a taper as reduced training before a goal race to maximize recovery while keeping fitness. 18. He says marathon tapering usually keeps frequency similar, cuts volume by about 50% over roughly two weeks, and preserves intensity through short fast efforts or race-pace work. 19. This episode suits runners who want practical pacing rules, race-planning structure, and taper guidance without chasing vague training advice. 20. It may be less useful for listeners who want a narrative story rather than detailed training and goal-setting discussion.
