Can you now reproduce road FTP on your trainer?

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

Many have said that they cannot reproduce the same FTP on their trainers as they do on the road. Much has been said as to why this is so. Mr Coggan says that once you get used to the trainer you should be able to duplicate your road FTP.

Now that you have had your trainer for a while has this proven to be the case?

I've just recently gone back to the trainer after riding outdoors all year. After ~6 rides so far on the trainer I think I am getting close. I also think my FTP is down from its peak in-season values, so it's hard to be sure if I'm totally there. So far, I've only been doing .85-.92 IF rides, but they're beginning to feel more 'natural' on each successive ride.

Oh, I can definitely put out as much power on the trainer as I can on the road for steady intervals. Obviously I can't jump or sprint as well on the trainer.

Dr. Coggan doesn't really recall saying that. What he has said, however, is that, due to the specificity principle, riding your trainer a lot (and keeping cool, of course) will likely help you "close the gap" considerably, and in fact many (although not necessarily all) individuals can generate just as much, if not more, power indoors compared to outdoors.

For me its simply been pychological I just hate doing long intervals on the trainer and the thought of CP60 on the trainer fills me with dread.... it maybe the same for others.

Where I live its very rolling with little opportunity to do long intervals (20min +) so I have to do them on the trainer.

I've tried to close the gap but I just have a huge dislike for long intervals on the trainer.

In competition I can produce ~10% higher FTP than either estimated on the trainer using CP20 or 'attempting' CP60 on the trainer.

I've no problem up to ~20min and have set all-time PB's indoor in that range but just around the 30min mark I start to fade - not a LOT but gradually and I ascribe that to excessive sweating & slow dehydration which limits my power output.

Just checked my 2006 data and my best indoor 30MP versus outdoor is currently 97%, 60 MP is 96% and 180MP is 95% - not a whole lot of droop really.
