I’m confused on the Computrainer 3D courses for IM Florida and IM Az. For example, IM Florida is as pancake flat as it comes with the exception of a bridge overpass. So, why does computrainer 3D show this as a big rolling hill type course when you pull up the course overview?
Kind of same thing for IMAZ?
Because there are some longer rises…really slight,
.
It’s all relative, that actual elevation changes on the course when you run the file are small. The elevation display at the bottom of the screen is not a 1:1 representation of elevation, otherwise it would indeed appear to be a mostly flat line.
I guess I just need to get use to it. It’s just confusing as hell at times with this thing. I’ll be riding up a .1 incline struggling to do 16 mph. There’s no way in hell that I’m only doing 16 mph on a .1 incline on a real course.
To me, the hills always seem tougher on the CT than on the real thing. HTFU!
no, no doubt I’m HTFU’ing as I know that the workout on the CT is going to do wonders for outside riding. It’s just getting over the mental block there of working your ass off to look down and have an average speed of 15-16 mph when you know that should easily be 18-20 in reality!
What is everyone’s typical calliberation number that you use?
right around 2.0 should work for you. I really recommend getting a trainer tire from the bike shop it makes a world of difference.
Also check to see how tight you have the back mechanism if you get that thing cranked down the wheel wont move as easy and your speed will be lower even though you are doing a ton of watts.

yeah, I bought one of the tires they recommend, just have been too lazy to change over to it, but I guess I need to go ahead and do that.
confused about the back mechanism though? I thought that is what controlled the callibration? ie tighter higher calib etc. is this one and the same, or two different things your talking about here?
I warm up for 15 minutes on the CT, then go for a press-on factor of 2.00. You might have to tighten or release the press-on pressure to get there once you have wamred up. If you don’t warm up (and thereby also warm up the tires and the CT equipment), the calibration will drift a bit until it is warmed up…if that makes any sense. Try this next time you jump on the CT. Press ± and spin up over 25MPH to check the calibration. Say it’s 2.5 or so. Hit the RESET button and warm up for five minutes, then press ± and spin up over 25MPH again…the calibration will probably drift down to 2.3 or so. Try it again in about 5 minutes and it will probably be 2.2 or so. Hence the need for the warm up. They explain it pretty well in the CT manuals.
The trainer tire is an excellent suggestion - but they can be a real bitch to get on the rim. The plastic doesn’t stretch like rubber.
Sorry i described that bad.
I mean the actual two pieces that lock the tire into place on the skewer. If you tighten them to much you actually can see the rear triangle coming together squeezing the cassette and everything.
You’re correct the little knob controls the calibration. The good thing with the trainer tire is that once you set it for a ride normally it stays that way for the whole ride the tire doesn’t really heat up like the other poster mentioned.
