Establishing the break

Similarly to stage 4, Ben made his way into the break within the first few kilometers of the stage, accelerating out of the peloton with a 1136W (16.4W/kg) surge. After 1:15 at 542W (7.8W/Kg), the break had a sizeable gap, which they maintained to the foot of the first climb of the day. You can get a sense of the effort from the speed; the group covered the first 37km at 44.4kph.

Early climbs

The following 60km of the race included 3 categorized climbs, with only short descents between each for recovery: Puerto del Pico (15.3km @ 5.5%) Cat 1; Alto de Grados (10.1km @ 3.3% %) Cat 3; and Puerto de Pena Negra (12.8km @ 4.3%) Cat 2.

Ben’s group rode a steady tempo up the first climb of the day, riding for 40 minutes and 4 seconds at 335W (4.8W/Kg). With the break’s lead steadily growing after the 5km downhill, Ben’s group began the category 3 Alto de Grados. Here he continued to ride at steady pace, averaging 303W (4.4W/kg) for 22 minutes and 9 seconds. Similarly after a short descent, Ben rode the Puerto de Pena Negra climb at 310W (4.5W/Kg) for 31 minutes and 4 seconds.

Climb Time (mm:ss) Distance (Km) Average Power (W) Power:Weight (W/Kg)
Puerto del Pico 40:04 15.3 335 4.8
Alto de Grados 22:09 10.1 303 4.4
Puerto de Pena Negra 31:04 12.8 310 4.5

Making the gap

Over the next undulating 70Km, the break’s lead steadily increased (to around the 10-minute mark), before starting to fall due to increased pressure from the peloton behind. At 30Km to go, Ben followed the attack of De Gendt, and in doing so set his many of his best power numbers of the day, including 30s (712W, 12.3W/Kg), 1 minute (574W, 8.3W/Kg), and 2 minute power (464W, 6.9W/Kg). This effort reduced the lead group to 7 riders.

At around 20km to go, Ben attacked from the group again with Mas, but soon dropped his companion by forcing the pace on a narrow cobbled climb. Here he produced his best 5min power of the race (396W, 5.7W/Kg). Now alone, Ben rode into final climb of the day, tucked into an aero position over the front of his bars whenever possible, and held a 1-minute 30-second gap going into the final climb.

Alto de la Covatilla (9.2Km @ 7.2%) HC

Riding alone, Ben put in a huge effort on the final climb of the day, averaging 363W (5.2W/Kg) for 28:46. After 5.5 hours of racing through another hot day in the Vuelta, he held onto a 48-second advantage at the line!
