Lindsay & Dina Lohan -- All Coked Up

Lindsay Lohan and her mom Dina grabbed their running shoes ... their track suits ... and a couple of bottles of Coca-cola as they hit the streets of New York today.

Yeah, Coke isn't the drink of choice when you're working out, but it beats vodka.

Lilo and DiLo rented bikes and cruised the West Side Highway in NYC ... then ditched the bikes and worked up a sweat during a quick run -- sodas in hand -- before hopping into a waiting SUV.

Feel the burn.
