Pilates 40:00 
Pilates session. Back quite stiff this morning; I think I would have struggled to run today, but eventually loosened up through this workout.
Found myself today looking through data sets to examine the frequency of days with average temperatures below -10 in Tabriz, Iran. (In case you're wondering, the context was reports of extreme cold and snow in refugee camps in places like northern Iraq and Syria, and Iran has decent data, which the aforementioned countries don't, so I thought Tabriz would be a good place to use to assess how unusual the last week has been - the answer being that it's probably an event you'd expect to see once every 2-3 years on average).
