Yes, the more effort you put into peddling the more strain on the chain. Also environmental factors such as dry gritty/dusty conditions will wear the chain quicker.Can the style of your riding make your chain stretch prematurely? Does grinding out the cadence put more strain on the chain rather than using the gears more?
I once took a younger bodybuilder colleague out for an evening ride over the local hills. He was strong enough to break his chain (mashing a 52/13 gear round on a climb! ), but trying to keep up with me half-killed him. (And I am not fast!)
I tried explaining to the body-building gear-masher that it would be better to spin a lower gear because if he carried on like that he would destroy the bike or his knees. He said that it felt weird to him to spin because he was used to 'pumping iron'. And 5 seconds later, his chain exploded under the strain!
He didn't change gear at all - that was the problem!@ColinJ Hate to spoil a good story but I suspect other causes behind that breakage. Maybe a very heavy rider going up a very steep hill could put enough of a load on a chain to break it but even that sounds unlikely unless there are other factors - it's usually shifting under load that causes breakages, isn't it?
Yes we know......Point of order:
Us feeble human beings are not capable of stretching a transmission chain of this size.
Elongation is caused by wear between pins and rollers.
If lubrication disappears then higher strain will accelerate the wear.
Sorry to state the bleedin obvious
I've recently broken a chain by overloading it, no gear changes involved. Granted it was quite an old one (9 speed) , but I pulled away from a junction, slightly uphill, in much too high a gear, barely over to force it over top dead centre, and 'bang' - snapped both side plates of an 'outer' link. First time it's ever happened to me.@ColinJ Hate to spoil a good story but I suspect other causes behind that breakage.

No damage to me, fortunately. And I was only 1/4 mile from home on morning commute, so able to walk bike home, get another bike** out of the garage, transfer contents of panniers, and still get to work on time.Hope you have recovered. No more long rides for you, then.
