If travel counts, then last year I left home at 4pm, drove 2 hours to the airport, 3 hours later got on a plane, 14 hours later off plane, 2 hour wait, on next plane for 10 hours, arrived hotel at 7am, had a shower, went to work, finished at 11pm. After a couple of weeks of meetings in various places I got up at 6, worked till 5pm, changed, to airport and back again.
Without travel, conference days are mad. Get up at 5.30, full face of makeup, bombproof hair, 6.30 breakfast meeting, 8am on the booth, talk to customers till 6 (some it is 7-7), then more meetings. One day I was still having technical discussions at 1am, and then back up the next morning to do it again
