Cycling 40:00  15.4 km (2:36 / km)
Still not 100% but on the way up, so felt confident enough to do a session of some kind, if not to venture into the humidity to do it. Original plan was to do a session on the stationary bike in the hotel gym in the morning, but what I thought was the hotel gym wasn't open then (in fact what I was looking at was a separate gym and the hotel one was elsewhere), so went in the afternoon instead (having gone for a walk in the park as my morning plan B instead). A bit tedious as stationary bike sessions are, but at least I didn't fall to pieces and it was good to get something passing for exercise.
The hotel pool (next to the gym) had a sign which listed the conditions which meant you were prohibited from using the pool. It's probably a relief that psychopaths are excluded. So are those with venereal diseases, although I'm not quite sure why; carrying out activities in the pool which could lead to the spread of venereal diseases would presumably be in breach of other rules.
The meeting wrapped up today; whilst still wondering what I've let myself in for, I've emerged from this week with a much better idea of what I'm supposed to be doing and when I'm supposed to do it. (Since I'm a bit of a glutton for punishment, one of the bits of the report I'll be responsible for is the one which deals with how much global temperatures have risen and how close we're getting to the Paris Agreement target of 1.5 C above pre-industrial - no pressure....).
