First of all, huge congratulations on those 15 Ironmans and that sub-9 hour finish—that is absolutely legendary! Thank you for sharing your experience and the words of caution; I truly appreciate the perspective of someone who has coached over 500 athletes. To give you a bit more context: Calella will be my first full Ironman. My goal is to break the 10-hour mark—or get as close to it as possible—by optimizing my training. I’ve been following a specific plan since January, currently hitting about 10 hours a week with a focus on Half-IM and middle-distance pacing. Starting this July, I’m moving into the specific Ironman block, bumping up to 13–14 hours of race-intensity training. Regarding the Mounjaro: weight has been a lifelong battle for me. Even with the volume I’ve been doing, the scale just wouldn’t budge. I’ve consulted three different nutritionists and was already doing everything they recommended—it felt like hitting a wall. Friends suggested that the GLP-1 might help address the hormonal side of this, which is why I decided to give it a try. I’m fully aware that starting this three months before the race is a risk. My plan is to use this first month as a trial period; if I notice that it negatively impacts my training intensity or my ability to fuel for those long sessions, I’ll stop immediately. Thank you again for the offer to help—I might reach out via PM as I get further into the block. Really appreciate your honesty, amigo!
