QuitanaRooster,
I noticed your post. I just did Ironman Florida for the second year in a row. I am a race director by trade and am 59 years old. I train 100 percent of the time on a Computrainer and have for 7 years now. I had knee surgery in 2000, bone replacement. As a result I increased my cycling time on the Computrainer. I normally do 200-275 miles per week on it. My bike splits at Florida: 5:03:52 in 2003 and 4:57:52 in 2004, both averages over 22.1 mph. So the answer is yes, the Computrainer is an excellent training tool if used correctly. You just can't get on it and ride, you need to work hard and challenge yourself on the many available courses it offers. Contrary to what has been said here, it's easy to set up and use( I carry one in my Truck for when I am away from home), setting up in 20 minutes or less. I could go on but I'll let you digest all of this, then write back if you have questions. If you doubt my times, check my splits on
www.Ironmanflorida.com. In 2004 I dropped out of the run due back spasms @ 16 miles on the run but that does not negate my bike split. In 2003 I finished in 12:23:20.
