Fabio Giudici lives a few kilometres outside Como in Lombardy and has been running for more than twenty years. At 42, he trains for around an hour and a half every day, which adds up to roughly 100 kilometres a week. At the 2025 Valencia Marathon, after three years of chasing it, he broke 2:30 for the first time, clocking 2:29:26. His next goal is a sub-1:10 half marathon.

This is the second instalment in our interview series with Tredict athletes and coaches from around the world.

Have a look at the first interview with Doug Jones from California, a "Tredict powered coach".

I asked Fabio to tell me about himself and why he has been using Tredict since November 2021.

Tell us about yourself: where are you from, and what role does running play in your life?

"Hi everyone, my name is Fabio and I live a few kilometres from Como (Lombardy, Italy). I've been running for more than twenty years, and I've been doing competitive sport for even longer. For me, sport is a constant: a refuge, and a place where I put my ambitions, dreams and desires, things that call for dedication, consistency and commitment. At the moment running is my only sport. I give it about an hour and a half every day, which comes to around a hundred kilometres a week. It's the most rewarding and the most demanding part of my day… even if, out on a run, I sometimes wonder what on earth possesses me, at 42, to put myself through all this."

You run very fast half marathons and marathons. Which races stand out in your memory, ones you won't forget in a hurry, and why? And what times did you run?

"Obviously, having been at it for so many years, I've got a lot of memories I hope to hold on to. My fondest, though, is definitely the 2025 Valencia Marathon, which I ran with the SportsShoes team. After three years of chasing it, I finally managed to get my PB under two and a half hours, stopping the clock at 2:29:26. That said, I probably won't forget pulling out at the 30 km mark of the Frankfurt Marathon the year before either. You learn more from your defeats than from your victories."

You've been with Tredict for quite some time now. What keeps you on the platform, and what does your day-to-day as a runner look like with Tredict?

"I've been on Tredict since November 2021 (I went back and checked: I just had to go to Evaluation, then Form, and scroll through the timeline), and although I've tried a few other platforms along the way, I've always come back. After a session I transfer the data from my devices and look at it in Tredict rather than in the manufacturer's app, because I find the interface much faster and more customisable. I've picked out exactly the metrics I want to see at a glance, and they're always right to hand. If, during a training block, I realise I don't really need one figure but am missing another, I can sort it out in a couple of clicks. On top of that, Tredict is compatible with lots of (I'd even go so far as to say 'almost all') hardware manufacturers, which makes me independent of their own platforms. And because there's no social media element to it, I'm spared the distractions and the addictive pull."

Some details of the Valencia Marathon activity in Tredict. Fabio ran mainly in his moderate heart rate intensity zone, tending towards the high zone, as the orange and red markings show. A true marathon race intensity distribution.

Do you use the intensity distribution analysis in Tredict to check whether, overall, you've got the balance of your training intensities right?

"Yes, it's one of the features I base my analysis on, and without fail I end up looking at it more closely whenever I end up getting that intensity wrong. For what it's worth, I'm always fairly attentive and focused in training, and I know what I'm doing and what I need to do. But sometimes the plan comes crashing into reality, and when that happens I go back over the data afterwards to understand what didn't work or where I went wrong. The feature I find most useful of all is how quickly you can create charts, both on the individual session pages and in the Evaluation. They give me a really illuminating overview, and from there I can quickly work my way back to the key moments."

Does it matter to you that Tredict comes from Europe, or are you not that bothered?

"For me, that detail is fundamental. I work in IT, and for a while now I've been trying to move further and further away from tools that don't have clear policies on how they handle data. Having a European provider gives me peace of mind, because I know my data is handled rigorously and my privacy is protected. Particularly when it comes to extremely personal data such as physiological readings."

Have you got any races lined up in the near future, or are you taking things a bit easier at the moment?

"My ambition at the moment is to take my half marathon PB under an hour ten. I'm only now getting back into the hard sessions after a spell of relative downtime following the Valencia Marathon. Having chased that result for so long, I needed to switch off properly, mentally as well, before I could get back to training seriously.

I haven't circled a target race yet, because I'll be trying to catch the ideal moment in my build-up, and the data Tredict gives me helps with that too."

Thank you so much, Fabio, and the very best of luck on the road to 1:10!
