My training plan goes like this ...
Monday - long walk at lunch | walk/cycle after work.
Tuesday - long walk at lunch | walk/cycle after work.
Monday: Oh, whoops. I've got a meeting at lunch on Monday so I'll shift the long walk to Wednesday. And I've got a thing on Monday evening, so I'll shift the walk/cycle to Wednesday as well.
Tuesday: Oh dear, I've got a morning appointment on so that'll be my lunch break, and look at that, they've moved my lecture to late Tuesday, so I'll shift Tuesday stuff to Thursday.
Wednesday: Aaahh ... someone has booked another lunch appointment ... and I am tired today. I'll move everything to Friday.
Thursday: Look at that, I've got to run errands at lunch today, and leave work early for a meeting ... no exercise today! Shift it all to Monday!
Friday: Must work through lunch and stay a bit late to catch up on things. Everything shifts to Tuesday.
OK, so we're starting the next week. Maybe I'll get lucky this time.
