I just got the Garmin speed/cadence sensor for my 305 and KK. To put it on TR all you need is the ANT+ stick. works pretty good. Easy.

Distance on a trainer will be accurate. Just like setting up any other computer you just measure the tire and you will be pretty close. It's just that without a head wind the trainer will require much less effort. So if your normal outdoor ride you do a moderate pace and hold 20 mph for an hour and go 20 miles.... well at the same effort on the trainer you can do 25+ mph so you will have an inflated number of miles on the trainer. Still nice to track, just not true miles.



I notice the exact opposite. The same power/heart rate/RPE on the trainer is always slower than the equivalent effort outside.

It REALLY depends on the trainer, and then it depends on how tight your wheel is. The only way to correlate speed indoors to outdoors would be to find the power you are outputting at a speed then extrapolate outdoor speed from that.

That would only work for a certain speed, not an average speed since the resistance curves for air resistance and the resistance on the trainer don't have the same shape.

We're working on some VirtualDistance stuff, that would do this for you based on weight, slope, air resistance, rolling resistance, inertia, ect. It's still going to be an approximation but it might be a little more fun.

I am guessing that this has to be a function of resistance, which would be why the comparison isn't linear.

Example: are you a light person? Do you crank up the resistance inside? Then it would be "harder" inside. Whereas, I am very heavy. Outside I go very slowly to drag my weight a distance. But inside, I can go "faster" because the resistance on my trainer may pale in comparison to my actual weight on the road. 

This is only my guess. This is why a powermeter can help I suppose, but I'm simply not going to buy one. Not in the budget at all.

Got it.... I guess I didn't account for all the variables and the resistance curves of the trainer. Ya, not much value unless you did controlled testing to see how you compared trainer to outdoors... then of course all that work would still not give you any real benefits.

X2 love it. Actually using the base plan now and its making time on the trainer a lot more productive feeling. Can't wait to see the improvement outside.

blindman10 - 2011-12-04 9:04 PM I don't know if any of you have tried Trainer Road yet, but it is in beta and I love it!  The OP mentioned it and I thought I would chime in.  If you have a higher quality trainer (I have a KK Road Machine) an Ant+ USB stick and the Garmin speed/cadence sensor Trainer Road will give you a 'poor mans' power meter. They have a ton of workouts or just free ride workouts and the instant feedback is amazing.  I know it utilizes the same data that a KK computer would, or simply using the power curve published by KK...but its great to have the computer feedback and log right there on your laptop!! Just my two cents, but if you are curious check it out while its still in beta (and free)!

I am anxiously awaiting the Mac version of Trainer Road.

I have power so would not use the TR estimate, but still think the idea of it is waaaaay cool.

I am trying to turn my coach on to it as well. I think the expectation is that eventually coaches would be able to write their own workouts for this. 

TR has a ton of potential.

Mac version has been about for a little over a month! It's waiting for you!! If your coach is itching to get some standard workouts in there have him post them here: http://support.trainerroad.com/forums/20356951-suggest-a-workout. That's temporary until we get the creating of workout stuff working.

Yay!

Had no idea!

Of course.....I had knee surgery a few weeks ago and am not doing anything at all except sitting in a cpm machine for hours on end.

Looking forward to trying it out when I am well again though!

Cool that you are on BT Nate.

You have a VERY cool thing going on and I wish you much success.

nate: I've been following the "Time Crunched" plan and I'm on week 5. I'll give you guys more feedback as soon as I'm finished with the program, but it's been great so far. I've been able to assess where my weaknesses are and look forward to working on them.

Still nice to track, just not true miles.

If you're riding at 25+ mph for an hour on your KK, then either (a) the rear wheel tension is _seriously_ light in your set-up, or (b) we can look forward to some storming bike splits from you next year. 25 mph on a KK typically calls for ~440w.
