2 days versus 2 weeks

I have covered the same distance in two days that took me two/three weeks going the other way.  Today was 12 miles and 9 locks.  Locks are for 1) taking the washing out of the machine, 2) making a sandwich, 3) grabbing a banana 4) getting a drink before keeling over with sun stroke 5) having a pee.  Some locks are too shallow to do anything other than work the lock!
And they say it will be hotter tomorrow.
