July 13th.
Started very early after a nutritious 5 minute breakfast of a tortilla and a cliff bar. Marcelo keeps us at steady slow pace through the dark with the occasional pause. The day before I was easily winded at a normal hiking pace.
The sun started to come up over Argentina about 2 hours into the ascent. Both lakes are finally visible together. The top is reached after about 5-5.5 hours.
