Holy **** cat 2/3 roadies. Get the **** over yourself not that strong. Noone stretches chains in a few rides it just not possible. If you're breaking chains on the road it's cause you didn't install them right.
I think we're in agreement that what breaks chains is not the strength of the rider. Except maybe in the case of our OP here with his massive guads. Next he'll be telling us he dials it up to 400 watts. (roadie forum humor, sorry)
OP, I suspect your chainline is a bit off. Either that, or the link isn't put together correctly. You aren't using some sort of quicklink/Masterlink are you? Some people like to take their chains off a lot and use these links but if not done correctly, they fail quickly. A lot of roadies have had this problem; chain breaks with little usage.
