For the second year in a row, my commuting mileage for the year has accounted for almost exactly half of my total cycling mileage. It's just a statistical coincidence, but interesting nonetheless. YTD, my commuting mileage is 3,024 and my total mileage is 6,087. So my commuting is 49.7% percent of total miles.

In 2008, my commuting totaled 3,635 miles out of 7,338 total miles -- or 49.5%. My mileage is off this year due to a lot more rainy days than usual in NC as well as a knee injury that forced me to cut back riding during the summer months, when I generally ride the most.

Commuting makes up probably 99% of my mileage. I'd like to ride more recreationally, but so far it doesn't happen much.

28.726%.

So near 100% that it makes no difference. I think out of the 20,000 miles on my bike right now, maybe 50 miles were not for commuting. Mostly just running up and down the road to check to see if an adjustment was correct, and one or two times going around the block (4 miles) or around a closed bike loop at a park with my son. There's really nowhere to GO around here, and all the roads are 50+ MPH so we never got in the habit of riding with the kids anywhere.

100%, I love commuting and cycling, but I am entirely too busy for recreational riding.

95%

At least half, maybe as much as 2/3. I'm trying really hard to get some recreational riding in, and touring. This year I did several short tours, adding up to a bit over 1000 miles, plus a few hundred miles of recreational riding, plus a few hundred miles of using the bike instead of the car --shopping, taking my daughter to soccer games, going for a hair cut, whatever. I have tried very hard to never use the car if the bicycle is a viable option.

2007 40%
2008 46%
2009 to date 60%

This year I've worked mainly five and six-day workweeks instead of four in the previous years. To make up for lost riding time, I've extended my commutes as often as practical. Also, my overall miles are down for several reasons, so commuting is a larger portion.

thdave

I like to bike around town, to the library and to shop. Also, I sometimes take a weekend ride or turn the shopping/errand trip into a longer joy ride. But those miles are dwarfed by my commuting miles.

I'd say 80% commuting.

genel

About 75%, unless I count the Sat morning ride to McD's.

Nobodyetal

98% at least.
I will occasionally take my older daughter and the mutt around the neighborhood on my beater MTB but the vast majority of my cycling time is commuting.

daven1986

Pretty much 100%, I do very few miles that aren't commuting.

2su

100% - I never ride just to ride. It's always to get somewhere.

closetbiker

it used to be 2/3s, but now commuting takes up 80% of my miles.

I thought when my kids grew up and moved out, I'd have more time to ride, but I have less. I've just become too busy to ride more.

Then again, I used to head out in inhospitable conditions because I considered my recreational rides as training, whereas now I consider these miles as enjoyment so am less inclined to head out too early or in inclement weather. That makes a difference.

Since I started riding/commuting this spring (early summer for all intents and purposes), I've gotten in 1500 miles commuting and a little over 200 in recreational riding. So about 85% of my miles come from commuting.

It's not for lack of desire to get in more rec miles, just haven't had the time to devote to the couple hours or more I'd really want for a meaningful weekend ride too often. One of goals for 2010 is to get in more recreational rides, though, and hopefully also to try a quick overnight/weekend camoing tour (two days - one out, one back). Maybe the miles will be a little more balanced next year. If not, so be it. Just one more reason I love being able to bike commute - it's an easy way to get in an hour-plus of riding a day for 5 days a week.

In the high 90s. Hard to say exactly. When the weather's nice I hitch on the Trail-a-Bike and go for short family rides. But that's less than once a week even in good weather.

Cassave

Like the OP, just about 50%.

truman

numbers hurt brain. me answer "most"

agarose2000

Wow - I guess I'm low round here. Probably commuting miles : <30/week. Road cycling miles: 120-200 miles per week.

It's interesting to me that so many bike commuters don't ride recreationally or not much. For me, one of my key reasons for starting to bike commute was to find the time for more riding on weekdays. I was already riding a lot on weekends, as well as trying to squeeze in rides after work on weekdays. My weekend/recreational rides tend to much longer than my commutes -- averaging about 40 miles/ride compared to 22 miles/day commuting.

AlmostTrick

This is an interesting question, and one that I've considered posting myself.

Do shopping runs count as commuting, or only rides to work? Either way it's high 90's for me for sure. I can't give an exact percent like lil brown bat, as some of my bikes don't have counters on 'em.

daredevil

The majority but I quit keeping mileage and stats a couple of months ago. Dutifully entered rides into Bikewire for a long time and then just decided I don't care about that stuff anymore. If I were training for something it might be different.

starla

77% apparently.

closetbiker

I consider those errands, not commuting. I don't even add those miles up, as I figure they don't add much to my total mileage. However, I've found I've prioritized errands on the bike to training rides. I'm a practical guy, and since I'm in decent shape already, and I'm not entering any events, I feel better using my bike for what I would consider a more practical purpose
