In this episode, Coach Jonathan Lee pulls back the curtain on TrainerRoad’s massive training dataset to show what actually separates faster, more consistent cyclists from the rest. He breaks down how TrainerRoad AI-recommended workouts are producing more power PRs while reducing workout failures, why the “50% rule” can help athletes avoid big rides that sabotage future training, and how even two hours of structured training per week can make riders perform like much younger athletes. The episode also digs into why your worst training weeks matter more than your best ones, how consistent “damage control” keeps FTP progressing, and what the data suggests about VO2 max intervals, 30/30s, threshold work, and over-unders for long-term performance gains. Throughout, Coach Jonathan emphasizes that these are observational analyses, not controlled studies, but the trends are clear: smart structure, consistent execution, and letting TrainerRoad AI manage the details can help cyclists train more effectively, skip fewer key workouts, and get faster over time.

| 0:00.0 | Welcome to the Ask a Cycling Coach podcast, |
| 0:01.6 | presented by Trainer Road. |
| 0:02.4 | I'm coach Jonathan Lee. Today we are going to do something a little bit different. We're going to look into some of the analyses that we have been running recently on our database. Now, we talk about us always making decisions based on scientific research and data. And we share quite a bit in terms of the scientific research that we're always looking at with training and performance on |
| 0:21.1 | how to get better. But on the data side of things, we don't share a whole lot of that all the |
| 0:24.4 | time. This might be risky for us to do, but at the same time, I want to share some of the stuff |
| 0:30.1 | that I've been analyzing recently and looking into, and I also want to be clear that there are |
| 0:34.4 | much smarter people doing much deeper analysis constantly here at |
| 0:37.7 | train a road but this is going to be a cool look at some basic training questions and |
| 0:43.4 | some insights that we can gain from our database it's a massive database it's really unique in the |
| 0:50.3 | sense that we have such high quality training data from so many athletes of all abilities |
| 0:53.9 | it's very cool so if this is something that interests you and if you have other in the sense that we have such high quality training data from so many athletes of all abilities. |
| 0:58.8 | It's very cool. So if this is something that interests you, and if you have other questions that you would want to ask of our database, maybe ponderings or thoughts you've had about what sort of |
| 1:03.8 | training would work better or different training outcomes and things you could do to influence that, |
| 1:08.6 | just drop them down below, Spotify or YouTube comments. And then we can look at |
| 1:12.6 | them and maybe answer some of those in future episodes. That could be pretty cool. But without |
| 1:16.0 | further ado, we're going to get into this. We have a total of five analyses that we're going to look |
| 1:21.3 | into. This first one basically started out with me looking at like, how is Traynor Road AI actually |
| 1:27.0 | performing? It's been out since early February. Now looking at like, how is trainer road AI actually performing? |
| 1:33.2 | It's been out since early February. Now looking at where we're at, what is the actual impact on athletes training outcomes? In other words, are they seeing PRs in their performance, not just in |
| 1:39.1 | their workouts, but then outside of it? And then also, you know, is it reducing workout failures? Because we know that that's the |
| 1:45.3 | thing when athletes are failing workouts. That's usually a big red flag for the training process, |
| 1:51.3 | not working as it should. So with that in mind, I want to go through and look at some of the, |
