Most of my weekly exercise comes from riding my bike. Most of my riding occurs on the way to or from work. And at lunch. So, I guess so, yes.

Commuting is my main exercise but I do a lot of walking at work. Great part of the bike' ing thing is doing the cruise around the neighborhood time with my 6 yr old.

Run, kayak, swim. All done by bike along with 90 percent of my commute. I log somewhere around 100 miles of training miles per week, 25-30 running miles. I probably am up near 20k rowing and another 10k swimming in any given week.

But then again, I'm sorta insane, mostly.

I also log around 40 miles a week of singletrack on my mountain bike. I have a six hour race next month.

I know there have been a few people at work who started to commute by bike, ended up stopping.

I guess this wouldn't be the forum to find out just what percentage of people who start to commute by bike to work, stop, but that'd be something interesting to learn.

I Googled "exercise drop out rate" and found that gyms expect a 20 - 30% drop out rate for new sign ups.

no running allowed..... doctor's orders...... bad knees...... i've already had one surgically rebuilt..... looking at potential knee replacement down the road..... ugh.


cycling is my main exercise (30 miles/day commuting + whatever for fun on weekends), though for 7-8 months of the year i also supplement it with a ton of kayaking. i try to get out on the water with every free moment i have (when i'm not on the bike) when the weather allows. i also go through starts and stops with fitness programs/weight training. i start it up, get kinda fit, then get bored after 3 months, give it up, let myself go, then realize a year later how soft i am, recommit myself, stick with the weight training for another 3 months, then get bored again and so on. the main problem i have is that i can't exercise indoors. it just feels wrong and i get so freaking bored being inside after awhile.

oh well, cycling and kayaking will always be my true passions. if i had easy, cheap access to a pool, i could see myself sticking with swimming as well because i love the water and swimming is such a great whole body workout.

I ride the 22-mile RT 2-5 times per week, do a 15+ minute weight routine every weekmorning, ride road or MTB on the weekend and have been running 7-12 miles per week, to train for a marathon in a few months.

Saturday, I injured my calf while running 7 miles-I had an identical injury to the other calf a few months ago that was finally healed. So the marathon training isn't really going all that well, but it's something to shoot for.
