Toronto 1/2 Marathon

So I was having so much fun last summer doing triathlons and accomplishing feats I would have never dreamed possible, so I decided to sign up for the two Toronto 1/2 marathons (waterfront and Toronto). Tomorrow is the bitter sweet end to my first racing season, as I set out to run the Toronto 1/2 Marathon. I should do well, I feel I am more prepared mentally. Unfortunately the weather has been so horrible, and I'm a bit of a wimp, so I haven't been running all that much. I am hoping that my summer of racing and training will allow me to accomplish more personal bests. My Waterfront time was 1:57:15, and even though it is a difficult course, I am really hoping to crack the 1:50 marker, and get close to 1:45, as I feel I can average 5:00 splits. I did that for about 15km at Waterfront 1/2, so hopefully I can do it for the Toronto race.
