Nope, I didn't do the TBN Toronto-Niagara-Toronto hairshirt ride. I have heard of this ride, and I have seen stats where some people have done this ride in 12 or 14 hrs. You need a good bike to be able to do that ride in that type of time. I was using a hybrid bike with 700 x 35 tires. Plus, I took my panniers with some food and a change of clothes for bad weather (I was expecting rain). The panniers obviously added weight. I also stopped every once in a while to rest, view the scenery, and tour some off roads. Plus, once in Niagara Falls I rested for about an hour before heading back to Toronto.
