Kilometre, is 1000 metres, a metre in American measure is ~39 inches. 100km is ~62 miles.

What is sarcasm?

If riding was the only thing I had to do and I could answer this, I would be a happier man. I try and try to arrange my life so I can ride as I wish and WHAM it gets changed.

But I really can't complain. I've got it pretty good and I've had it great.

Right now I'm hitting about 80-160 k per week at a 28+kph average. 15 years ago in this locale it was 160-300 kpw @ 34+. Getting old is humbling.

But it beats the alternative!

I'm on the Eddy Merckx plan, "ride lots". If that's good enough for the cannibal, it's good enough for me.

If it is a distance that you have set for a exercise program then I would say if the total was 100, or whatever, you would need to divide it up per day or every other day as to get the best benefits. Doing it all in one day would not be as beneficial as say every day or every other day. Like weight lifting. you wouldn't lift x amount of weight all in one session and rest the other 6 days.

So for me if you are doing biking for exercise then ride as often as you can and do not worry about a total mileage per week, just ride.

I think we're saying the same thing. I was simply pointing out that for MY goal of 100 miles a week, I take the miles when I can get them. Getting them is more important to my feeling of well being than how I get them.

It would probably be best to break up 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 km goal into a few kazillion shorter rides.

In a given week I may ride a fixed gear bike for varying distances. However, as I haven't had a vasectomy or similar procedure I don't ride "fixed" for any distance.

Well, this is the thing, every winter I set a goal of how far I would like to ride that year, and every year something throws a monkey wrench into it.

2006 - crashed, April, missed 6 weeks,
2007 - blew out back at work, April missed 5 weeks
2008 - it snowed from November until it switched to rain in April, rained until November when it switched back to snow.
2009 - see 2008 - got a trainer for the winter though - now just need to start using it.
2010 - hernia operation, June, miss 4 weeks (minimum).

Today it looked perfect, 17℃ and sunny, checked the weather, 30km/h winds, for safety I usually skip it, if the wind is more then 25km/h this time of year, even if you did nothing, but ride the trainer all winter, even moderate wind is something your not ready for 3 rides into the outdoor season. especially when your on a relatively upright mountain bike. Looks like either rain or snow all next week, rain I can deal with, in summer when it's a relatively warm rain, this time of year when the rain is cold, no thanks. Snow, not with the idiots that they hand drivers licences to in this town. So, outdoor this week, back on the trainer next week, been thinking of setting it up in the garage, and riding there for some training, now that it's light out later, even on days where the weather stinks, I could get some ride in. It's too cold out there, in the winter, but I could now or in the summer on off weather days. We don't really have space for indoor riding, maybe if I win the lotto tonight...

I can relate. I returned to cycling in September 2007 after 3 decades of inactivity. Took a year to really get up to speed while moving from old MTB to old road bike to new road bike. By late 2008, I had my wife riding with me and we were doing rides up to 50 miles. Bought us both nice road bikes and it looked promising.

Then, in January 2009, I was rear ended in my work vehicle and got some serious whiplash. I rode as much as I could stand but my distance plumeted. Then, in mid-March when my neck started to feel better, I herniated a disk in my lower back. That kept the distance down for a while more. Then the flu hit. And summer came, then we took some vacations, then my older son started college, then life got in the way in a dozen different ways.

I'm now, finally, feeling good and working to get some consistent miles in. Getting my wife back up to speed will take a lot more work. Winning the lottery would certainly open more possibilities but, as it stands now, I just get in miles when I can and encourage my wife to tag along.

Ya, this is goofy, when i am not crashing i ride between 120 to 180 Miles a week. I chose the first one because i thought its just one day out of the 3 to four days a week that i ride. I have 156 miles this week and will ride tomorrow and Saturday as well.
