Say if your short on time one day of the week and you have a scheduled bike in...

You only have a short amount of time but you still want to get your bike workout in. What would be the minimum amount of time required to ride your bike either on the trainer or the road to get a benefit from it?

Will 40min-1hour bike be worth it?

All work "counts".  If pressed for time, ride harder.

If you can ride straight for an hour (not a lot of lights to interrupt you, etc) outside, I'd say it's worth it.  Even 45 minutes.  Less than that, i stay on the trainer.  As for a trainer, I say anything 40 minutes and up is worth it, maybe even 30 minutes, since you can really concentrate on intervals or drills (and people usually say time on the trainer is worth 1.5 time outside...  not sure if that's true)

A large percentage of my bike training is short (30 or so mins) because it is my commute. I try to push hard and attack the hills and think I get a lot out of these. I treat them like a regular workout. Sure, I would like to ride more/longer, but with these with an occassional longer ride thrown in I get in some miles while keeping peace at home (car commute takes 20 mins, bike takes 30...so everyone is happy because I am not off training all the time :-)) Having said that, I ride 2X/day on days when I ride to work (to work and from work), so it adds up to an hour+ on those days so not exactly an apples to apples comparison with your scenario but I would say that if you did 7X30 min rides a week, you would get faster than if you didn't. And if your choice is to not ride because you can't do more than 30 mins, or do the 30 min ride, do the ride! I think 40-60 mins can be a very good bike workout if you push hard. Lots of people seem to think that it is not somehow and I saw in Triathlete magazine in a recent issue that a lot of triathletes think bike workouts less than 90 mins in duration are worthless, but I beg to differ.

I take my bike to work with me every Monday and ride on my lunch hour 3-4 days a week...40-45 minutes at a time.  I do my longer rides on Sat. or Sun.  

I am relatively new...so I can see a BIG improvement in my biking since I started doing this...maybe it's different for more seasoned riders... but for me...40-45 minutes is certainly worth it.

I've had this same question.  The pool I use is 2 miles away.  I always drive because I don't want to deal with locking my bike up, dealing with a helmet, backpack for the towel, etc., for a 7 minute bike ride.  And my commute that I do 2 days a week or so is 30 minutes each way, but I'll often take a longer detour either on the way to work or on the way home.

This sounds literally exactly like me.  Well over half of my bike miles are accumulated in ~30 minute chunks commuting either to/from work or the pool.   I haven't done a continuous ride over one hour since my last half-iron race in mid-June (raced Olympic distance and shorter every weekend since then so there's been no time for longer rides).  I routinely do 26+ mph in short course races and have split well under an hour in Olympic distance races on this program so the short rides must be worth something.

That being said, since I'm not racing the next two weekends so I'll for sure get in a couple 4+ hour rides, but whenever I hear someone try to argue that any workout has to be a certain duration to be effective I have to try really hard not to fall over laughing.
