I live in Tallahassee, but mostly ride rural roads east of the city. It's pretty much impossible to avoid all hills here. Tennessee St. is the least hilly, but not a good road for riding (I wouldn't ride it in the city). From where you are, I'd take Pensacola east to Ocala, north on Ocala to Tharpe, east on Tharpe to John Knox. Take a left on John Knox and it leads to the Tallahassee mall.
