ddac - The distillery is a cool place to check out but not really near much else. I'd also suggest the area around Kensington market. From there you have China Town, Queen West, and the Annex all within a 10 minute walk and all of which are pretty fun areas to walk through.
And for Hill repeats, I've been just waking up quasi early on weekends and riding from the bottom of Yonge Street and going north. It's not traffic free but the cars are alright on Yonge Street mostly and there's a good bunch of hills to tackle.
