Both are forcing adaptations on the body and demand absurd amounts of fuel. You can't eat and rest at the human limit twice over while developing yourself in two different ways.
That said there is some overlap in mass and endurance in that some things are so light for a big guy that they effectively don't cost energy. Knowing this you could be big and cover ground, but not at anywhere near an impressive speed.
