Former NFL running back Isaiah Pead ain't gonna let a life-changing accident rob him of his athletic dreams ... telling TMZ Sports he's now on a quest for Paralympic gold!!
We spoke to Isaiah 16 months after he lost most of his left leg in a car crash ... and he told us he's planning on hittin' the track in hopes of crushing the 2020, 2024 and 2028 Summer Paralympics.
"If they let me on the track, I'm goin' for the gold, period."
Pead says he's still in the early stages -- getting a prosthesis and sponsorship -- but he's confident everything will come together.
