After the attack, he’s able to sustain a higher pace—likely thanks to a higher CP among other factors. Simply outstanding what UAE is achieving with their riders’ preparations. It’s incredible to see the improvements of so many already top-level riders—like Narváez. Sublime.

In that regard, I believe investing in a blood lactate analyzer is essential and relatively inexpensive, especially when you consider the cost of other devices people commonly spend money on.

One key aspect for us has been intensity control through regular lactate measurements. This has helped Albert gain a much deeper understanding of himself, and it’s allowed me to identify trends in his profile without needing to conduct frequent tests.

With that performance he has finished a mega first part of the season:

- 10km PB (36:14) -1'30 season PB
- HM debut (1h23)
- Half Ironman debut (4h32)

I’m very proud of Albert’s journey. We started with a 40-minute 10K and a 20-minute power output of 225W at 65 kg body weight. To put things in perspective, today he was able to ride 90 km at 195W (now at 60 kg) and then run a hilly course at 4:18/km pace.

Today I did:

5 x 1600m/60”
Borg: 12

I always check the external load once the session is finished. Today, my average pace was 3:55. The trend continues to be positive.

I really like these long-term cases. This clearly demonstrates that the approach you’re taking is effective. As you rightly point out, it’s not just about progress over time but also about the solidification of that progress.

Road to 6W/kg 📈🙌

A highlight of the experience was the practical session in the hypobaric chamber at Bellvitge, where we simulated conditions at 5000m altitude and conducted the hypoxic test.

This experience raised many intriguing questions that I look forward to exploring further in the future.
