13 hours a day? Sooner you than me.

That's a fairly typical day for a Home Counties London commuter - leave
home around 0630, get home around 1930. You're only working for 8 of
those hours roughly, but it's still a long day out.

I don't do daily commuting but recently I've attended several all day
(which is roughly 9.30am to 6pm, or 2pm to 10pm) sessions in
Westminster, to which one can add getting on for two hours each way.

Long days in the past mainly at conferences, where work starts over
breakfast and goes on all day until 8 or 9pm.
