Could it be that the water you displace in front of you is magnified as approaching the shallow end due to slope on the pool floor. Bit like s tsunami cresting as goes up the shelf and onto shore. This 'extra' water is bounced back off of the end of the pool causing more of a current.
When going shallow to deep the water being pushed in front of you had more room to dissipate.
When I swim 25 metres in the pool from shallow end to deep end it takes me exactly 21st strokes, doing front crawl.
When I swim back the other way it takes 22 or sometimes 23, same stroke.
Can somebody tell me why?
Swimming pool circulation pumps may cause slight differential in resistance to the swimmer in each direction. The Barcelona pool in the World championships 2013 was found to have this problem. It is far less prevalent in modern pools, but never the less it may affect a finely tuned athlete as yourself.
In the olden days I used to compete. My home pool was the old Downham which was a glorious 40 yards. The pool pump was at the end of the pool and if you got that lane, it was like swimming against a tidal wave. Obviously, I was always saddled with it, and it is the sole reason why I never went on to Olympic glory.

I think it's something along these lines, probably to do with the pressure in the deep end. I'll have to try a pool which is shallow at both ends. It's been bugging me for a while.
I swim most days and have never, ever thought to count my strokes, which is surprising as I have run out of things to think about (does anyone else remember how many lengths they've done by counting in player shirt numbers?) - I shall test out Donyngs Recreation Centre's pool and see if this phenomenon exists there.

I swim most days too with a minimum target of 60 lengths. I don’t generally have a problem of remembering which length I’m on. I sometimes think of the fractions and percentages to get me through. E.g. It seems to help knowing that I’m two fifths through at 24 and fifty percent at 30 etc.
The only times that I forget which length I'm on is when I try to count the strokes I’m doing during the 60 - I evidently do not have a dual processor in my brain.
Is it too sad to admit that I sometimes count other people’s strokes per length too?
ATMs that differ in their procedures in different countries. UK = tap away, get card back, then money appears. The last foreign land I lived in = tap, cash, then card back.
Or more accurately, tap, cash, walk away with cash. Much later go back to bank to collect and pay charge for, card.
if i'm not on a flat surface, i can't keep it up all night. I'm too much of a square peg in a round hole. Carry on Camping. (Sid James was in that one)
Why veggie ready made food is made to look like sausages, bacon or a steak and not mushrooms, cabbage or chestnuts.
It's a transitional thing for those with a history of eating meat. It does help while you discover how to change your diet. And veggie sausages are very nice too!
the amount of money women are willing to spend on crap
my wife proudly informed me this afternoon that she'd only spent 28 euros on 4 bottles of shower gel- she genuinely thought I'd be impressed at how well she'd done spending that on essentially the same stuff I would've got in Sainsburys for a fiver
then I just had to stop her from buying a small piece of sponge for 5.50. what goes through their minds?
How women can spend a whole afternoon, or even a day, looking for an item of clothing or pair of shoes costing £100 or less yet demand an instant answer as to whether or not an offer should be made on a property costing hundred of thousands of pounds and get the hump when you suggest a bit of think time might be beneficial!

It's uphill on the way back.

Are you just rubbish at counting ?
