Did some searching on this site and google and could not find anything at this position.

Did two hard trainer rides (yesterday and this am) and am getting a sharp pain just above and to the inside of both knees. It seems directly related to the constant sit & spin only that the trainer mandates - no standing and no coasting. Hurts while on the trainer and more going down steps after.

It's seems to be right at the end of that huge inside quad muscle. From pictures, it may be the upper end attachment of the medial collateral ligament (MCL), but I think it is too far forward for that. Feels more like the tendon (shown in the picture below) that is medial to what is labeled as the Quadraceps Tendon.

Any ideas/experience with pain at this location?

TIA,

Had the same problem. Lower saddle and/or move it forward.

I feel your frustration...just came from my doctor/triathlete who diagnosed me of having tendinitis in both my rectus femoris muscle and IT band. My pain was more centered on the quad and graduated to the IT band itself. Factors were coupled with low rpm,hills or big gear work,often coupled with a cold day.

Had the same problem. Lower saddle and/or move it forward.

With both knees or quads (sounds like VMO to me btw) hurting IMO means typically the saddle is too low and/or too far forward so you need to raise and/or move it back. I would do it (height) in 3mm increments and reassesses. If you slide it back, try ~5mm at a time which effectively raises saddle by ~1.5mm for each 5mm aft movement so you can slide back 5mm and raise just under 2mm at the same time, if you like.

This is based on my own bitter painful experience.

Defitinely sounds like a tight IT band ( Try stretching it) but the best advise I could give you is to see a Sports Doc and don't fool around with it.If advise from the web doesn't work the down time or pain isn't worth saving a few dollars by not seeing a specialist.

Dial down the workouts until the pain goes away. Are these the first "heavy duty" workouts of the season? If so, you can expect some pain as your body gets used to being beaten up again.
If it doesn't go away, see a Doc.

I am not a doctor, I only play one here on the 'net.

I assume it is a bike that has been on the road with you before with no pain????

I would not change anything on the bike except the gears, trainers can beat you up.

Doing my 2x20s in ergo mode on a CompuTrainer. Gears don't matter.

I occasionally have felt a twinge on the road (and indoors), but nothing like this time. This is also by no means my first trainer workout. Between spin bikes, trainers and CT, I averaged 1.8 hrs per day last winter (1.8 average means some 5 hour days). It was one of my first on this bike on a CT.

One problem is that I can't stand up on the CT. There isn't enough 'instant resistance' to keep the pedals from just flopping down. Fly wheel is too small?

??....I don't have any trouble doing sprint intervals on a Couputrainer. I just set up my sprints on a uphill. If I want to do a max watt sprint workout, I'll have a long downhill @ 10% and work my rpm's up to 120-125. The sprint will start just after the slope jumps up to 8% for 200 yards. The downhill section will be around a mile long. I'll do ten of those intervals in a normal workout. With a half hour warmup and a 15 minute cooldown, it gives a fairly good workout.
