Never done it every day, but I have done a bike to, run fr, run to, bike from rotation. I bring in two sets of clothes and lunches on the bike, then leave them and the bike overnight. Run in the next morning, then ride home.

Also works better for me as it's about 6mi OW for my commute, two long to do twice a day, every day...

Just takes planning: extra clothes at work, some recovery food tucked somewhere, sometimes leave bike in my office than run in/bike home or vice-versa. Sometimes coordinate with my wife for ride home. Sometimes drive in, run home, run or ride back in next day, etc. It's definitely the way to go to squeeze some workouts in during a busy schedule, presuming you have the right distance. I'm lucky to have a good 6 mi run course or 10 mi bike ride with some climbing to make it worth my while. Also have to be safe b/c, especially in the winter, it often means being on the road in the dark and drivers are bad enough in the day. I avoid a backpack with running (though not with bike) b/c it really screws up my back.

thanks for the replies!

the alternate days thing might work well for me; that way i could mix things up and still have a way to carry a limited amount of clothing. i wasn't excited about the thought of driving a week's worth of clothing to work.

i saw this bag and wondered if it might work for me for the light running pack

i don't have a camelbak already, but i'm guessing what you guys are referring to is similar in size to the bag above

I could run to school, but I bike it on my touring/commuting bike almost daily, never ran it even though I could once/twice a week as it's my target of 8 mile mark and just use the school gym for the shower/change.

Never rode the race bike as I'm too scared of vandalism/theft and a lock on it would look funny, but the old touring/commuter bike isn't much a prize to thieves so its like an old fat girl at a bar full young naive kids.

I'm pretty lucky I guess, plenty of time to train, just need more inspiration. My friend just did Lake Steven's 70.3 and finished sub 6, great for him and I'm so J I'm using that to inspire me now.

I am only about 6 k one way from work, so I bike or run daily. I drive in everything I will need for the week on Monday. I use the CamelBack M.U.L.E. for daily essentials like wallet, lunch, swimwear, etc.

Occasionaly I will just pack everything I need for the week in a rucksack and walk it all in on Monday. Not really a workout, but gives you time to slow down and enjoy the enviroment. It works out well for me that way, as Monday is my training off day.

JfromJacksonHole, i like that bag

i'm guessing that, at the end of the day, this will boil down to a fit issue...whether it chafes or not, how much it bounces etc

does your pack end up needing washing after a few weeks? every week? do you ever wash it?

My commute is 23.3k minimum, but I vary the route so it ranges up to 29k even 50k when I want the extra mileage.

I hate cycling with a backpack so I have a carrier rack on my commuter bike but usually I just have stuff at the office.

Bike commuting is better for the body, the wallet and the planet.

PoC

I just came out of retirement (job was too good to refuse, ok short lived 2 years was enough) and started biking last friday (started last Monday). I am only about 10 miles with a bike lane 90% of the way. Have a shower at a gym in the office building and just leave my towel, flipflops and shampoo etc in a locker. I did finally break down and get some paniers and a rack because I have a laptop now to cart around. I was SOOOOO excited to start riding in a to work again!

Ok, to the point. Hubby suggested I could run to work once in a while. Once I get my mileage back up I probably will but more likely bus in and run home or the reverse. My camlebak M.U.L.E has worked great for 3 Rim to Rim runs of the grand canyon so I will use that.

J, you've got packing down to a science!
Brit, welcome back to 9 to 5
kylie, that's almost too close...work is going to start coming to you!
