We mention one of the comments on the Dynatech blog, to provide some information.

Raúl Martínez, Adrián Uclés and Fran Lorente make it to the top of the Vallunaraju

The day before setting off to Peru, we said our goodbyes to Francisco Mateo (Dynatech-elevation General Manager); we were talking about the reason for his special interest in climbing and its consequent sponsorship.

Originally, today’s intention was to rest; however, we have the will and strength to continue with the acclimatisation and have therefore decided to set off to the Vallunaraju BC at 5686 m. We intend to climb up to the 4300 m BC today and tomorrow, at 3 AM, get up to go to the Vallunaraju and keep on climbing as much as we can; we do not have a particular height in mind, we just want to acclimatise.

After being at 3800 m. yesterday, today, following the aclimatation process, we have been at 4500 m. in the Churup lake. It is a beautiful place. The Churup mountain, at an atitude of 5495 m., gives his image to the lake and that one looks like a decorative accesory as appropiate. Both of them are places of special beauty.
