Resurrecting this thread! I'll try and sum it up and bring everyone up to date so you don't have to re-read the entire thread...

Last year I had just got back into biking and was doing long-distance rides once a week as well as commuting and doing shorter mountain rides weekly. My end goal is to do 200km from Ottawa to Montreal, alone, unsupported. My longest ride to date was 82km last fall and it nearly killed me as I was unprepared for the cold and the dark. Shorty after that I had a nasty, NASTY fall on my tailbone so I had to end my season.

Fast-forward to this year...

Was slow to get started and haven't been riding as much per week as I did last year because I've been super busy with a new job. I've really only been commuting and doing my long-distance rides once a week if I'm lucky. I completed 70km today, the longest so far this year, and it was quite frankly a breeze (though my last ride of 63km wasn't as easy - I think it was the heat).

So, what I'm wondering is when should I have a go at the 200km? How much more do I need to increase to before I can tackle it? Do I have to hit say 150km first to be ready? I know I haven't given a lot of info, but I really have no clue so any advice is welcome. If I need to provide more info just ask!

I'm 37, 5'8", 150 lbs in good, but not amazing shape.

Thanks!
