This week, Emma gets stuck in an elevator, a red squirrel gets way too close for comfort and Steve continues his transformation into Old Father Time.

All the while, Steve and Emma continue to get into the rhythm of their hike. They ache a little bit more and they whinge and moan a little bit more but, underneath it all, they are improving with every day and planning an even faster hike.

Emma now wants to be at Santiago by November 10, so Steve has set a tougher schedule to see if they can achieve their desired outcome. So far, the two of them are getting to grips with the new plan. What could possibly go wrong?
