We're going to a lecture by Mark Beaumont, the chap who cycled around the world and recently cycled the length of the Americas, climbing Denali and Aconcagua along the way. Other tour dates here.
I'm particularly interested as he filmed both rides himself. Both were turned into BBC TV programmes.
I've spoken to some former BBC colleagues who worked on the subsequent TV programme and I hope to learn quite a bit.
However, as I'm starting to get itchy feet to tackle another big trip myself, I suspect this will do nothing to calm that desire. Quite the reverse.
