In the improvised workshop nearby, the Lidl-Trek mechanics worked on their new bikes; next door Decathlon–AG2R La Mondiale did likewise. “You should see Teide [in Tenerife],” the Lidl-Trek performance coach Aritz Arberas Pampin says. “There is only one hotel [at altitude], so every morning at 10am it looks like the start of a race.”
On the 20-kilometre road to Canales, the Lidl-Trek riders descending in their wind-breakers and gloves, we passed Visma-Lease A Bike, already hard at their efforts; later, on the cursive roads that rise towards Pico Veleta (3,398 metres), the Bora-Hansgrohe riders Jai Hindley and Primoz Roglic. We were following a group that included Tao Geoghegan-Hart — set to lead the team at the Tour until injury and illness intervened — and Giulio Ciccone, the Italian who will be co-leader in Geoghegan-Hart’s absence.

To ensure each rider was working in the correct power/heart-rate zones, Arberas Pampin and his team performed lactate tests at the beginning of the camp. “They do a climb with more intensity and after each step we take a blood sample and we see the lactate concentration in that blood sample,” he says. “With that we create a curve of lactate accumulation.” In this, he explains, you can see the numerical evidence of why the leader is the leader and the domestiques the domestiques.
“The highest-level riders have a better lactate curve — more efficient, all the way. Racing is another thing … you can have two riders with the same lactate curve but when you put them in racing, one is performing better than the other. In racing you also have technique, heat adaptation, carbohydrate absorption.”
At altitude, heart-rate, not power, is often the preferred guide to exertion levels. Rather than the input (force on the pedals), you read the output (how the cardiovascular system is responding). The team were also monitored regularly by blood tests — measuring Creatine Phosphokinase (CPK) and urea, which indicate fatigue — and their training stress was tracked. And there was simple oral feedback. During training, the Dutch rider Sam Oomen — who joined from Visma-Lease A Bike ahead of the season, and struggled with his bike position — arrived at the window of the team car to tell Arberas Pampin that the mechanics had cracked his set-up. “It feels like I have come home,” he says.
