Winter Running

I used to run 20 years ago. It was just for fun and not very regular. In November of the last year I have started to run with a goal of running a marathon in the future.
Initially I didn't know when it will be. I want to make my running safe, injury free and pleasant. I am not going to rush. I am planning to run full marathon not earlier then in 2008. I would like to run my first marathon below 4 hours. To run marathon comfortably in such time my preparation would require running many kilometers and it means that it is huge time commitment.

For this year I have set a goal of running 5 km, 10km and 1/2 marathon races.
I have already registered for 5 km race, Frosty 5K in Burlington, on 04 of March. My time goal is to make it below 22 minutes. My dream goal is to make it in less than 20 minutes, but I don't think that it will happen this year. So far I am running over 30 km per week. My longest inside run was 16.85 km and my longest run outside was 10 km. My current log is posted on coolrunning.com.

I have also registered for 10 km race, Canadian Tire 10K in Mississauga, on 12 of May. My goal there is to run under 50 minutes. It isn't very ambitious, but I think is reasonable for the first time.

My biggest race of the year will be 1/2 marathon, Niagara Falls International Marathon 2007, on 28 of October. 1/2 marathon starts and ends in Canada. My goal is to make it under 2 hours. Full marathon starts in USA and ends in Canada. I think it is the only marathon starting in one country and ending in another. I am hopping to run this race one day.
