Do running repeats on the bridges you ride and it'll kick your butt, but it will also make you stronger on your bike.
Sport specificity.
I'm sure running bridges can make someone faster, than no training at all.
That said running is not optimal training for bicycle racing.
My bet is that your bridge running improved your general fitness, and therefore your climbing, because you were pushing yourself harder bridge running, than you are riding.
The key again is sustained power output. Doing 2x20's on the flats at FTP is going to help way more than running possibly can.
