In this episode of Endure Prime, I sit down with JD Tremblay to talk about EpicDeca, ten Ironman-distance events in ten days across the Hawaiian Islands.

JD shares what it took to prepare for such an unusual challenge, how he managed the physical and mental demands from day to day, and why recovery, pacing and a strong foundation mattered so much. We also talk about the role of his crew, the importance of faith and purpose, and what happened when the event was over and ordinary life returned.

The conversation then comes back to the kind of training most runners can relate to: staying consistent, avoiding doing too much too soon, knowing when to push and when to back off, building fitness through easier training, and using strength, recovery, sleep and nutrition to support long-term progress.

JD also reflects on motivation, longevity and why the work that matters most is often the work that looks least impressive.

If you found JD’s perspective valuable, you can leave him a rating and short review on SpeakerHUB here:

Strength training can help runners. But if running is the part of training you enjoy most, how much space should strength really take up?

In the fourth episode of The 5 Pillars of Better Running, Bjørn-Ivar looks at strength training from a runner’s point of view. Not as a separate fitness project, but as something that needs to support the running rather than take over the week.

The episode explores what strength training can actually add to running, including improvements in running economy, strength and performance, and why those benefits do not necessarily require an increase in VO₂max or body mass.

It also looks at the practical side. Does strength need its own hour-long session, or can a short session added to the end of a run be enough to make it worthwhile? How does the answer change for someone running three times a week compared with a more serious recreational or highly trained runner?

Age is another important part of the discussion. Strength may begin mainly as a performance tool for younger runners, but as we get older, maintaining strength and power becomes increasingly important in its own right.

The episode also takes a closer look at one of the most common claims around strength training: injury prevention. The research is more complicated than simply saying stronger runners get injured less, so the focus is on what the evidence actually supports rather than making promises it cannot make.

And finally, Bjørn-Ivar looks at what useful strength training for runners can actually look like, why simply creating more endurance fatigue in the gym may miss the point, and how strength can fit into the week without compromising the running that matters most.

Running is still the main thing.

Strength is there to support it.

This episode continues The 5 Pillars of Better Running with pillar three: HARD TRAINING.

We look at VO₂max, threshold, running economy, interval structure, recovery and load management, and why different hard sessions create different adaptations.

For masters runners, the focus is not on avoiding intensity, but on using it well enough that the body can absorb it.

The goal is not maximum fatigue. It is the right training stimulus, placed in the right context.
