These are good points. A French coach called out Roche last week about his crazy version of heat suit training and wanted to know why a coach would promote such a dangerous method of training:
When asked again to answer the actual question, he goes on to say: "Great points and questions! I think being honest and open about what’s happening behind the scenes is important, while also being honest and open about extreme uncertainties and risks. Endurance sports have been plagued by a lack of transparency forever, and heat suits have become standard practice for cyclists, while runners have been doing versions of it for decades. I always try to share every disclaimer and to avoid being prescriptive or simple-minded about complex biology subjects, but my main goal is to democratize research and practice, trusting people to make their own decisions with their doctor (and coach if they have one). The heat suit research and practice is substantial at this point. It might all be snake oil in the long run, and it’s definitely subject to individual response variation, but I don’t want to hide reality from athletes to protect them from themselves."
Which makes no sense at all! He then went on to talk about this Instagram post on his Patreon podcast. He criticizes this coach for being the kind of coach that doesn't like new things! This is a weird thing to say as heat suit training is an old method that's been shown to be dangerous if done in the way he's doing it.
So, yes, you are right. And this heat suit nonsense seems to be yet another example of Roche acting in an irresponsible and over the top way that's going to get people hurt. He doesn't seem to care that his behavior will be copied and people will get injured and over-trained. It wouldn't surprise me if this stuff backfires on him though - a heat suit AND a weight vest - I'm no expert but that seems unnecessary?
The 'transparency' argument is lame. It's a meaningless, or at least a deeply compromised, idea. Transparency these days is just a brand management tool, rather than a means to reveal uncomfortable truths. Roche let's us see exactly what he wants us to see, and a lot of what he does seems staged. He seems more concerned with what goes viral and boosts his brand and sponsors, rather than what's authentic.
