The royal chatted pleasantly on camera while trekking through the cold of Antarctica on Wednesday as part of his goal to raise awareness and money for the Walking with the Wounded charity.
In the video above, Harry, 29, says he's not feeling "too bad," adding, "The wind has dropped down, which is quite nice … We just got into the rhythm and it's almost finished."
He says he's expected to reach his destination on Friday.
Before his adventure, the new uncle joked that his brother must be "quite jealous" because his trip to the South Pole allowed him to "get away from his screaming child," Prince George.
Harry and his team are braving temperatures as low as 58 degrees below zero, but they are not alone. His group is making the trek with two other teams, captained by actors Dominic West and Alexander Skarsgard. Initially the teams were racing against each other to the South Pole but that was suspended on Dec. 7 due to safety concerns.
