    Fluid trainer temperatures

    I've used a fluid trainer for many years. I have always noticed how hot it gets after 30 minutes or so. You can actually smell the heat at times. So today I decided to pull out the infrared thermometer and measure the temperature. Here are the results:

    After 10 minutes

    After 30 minutes (19.5 mph avg at the end)

    I'm guessing the temperature was still increasing but I was out of time. Still, way too hot for comfort.

    My trainer: TravelTrac 2000

    Anybody else have data on how hot trainers can get?

    Any time you add resistance over an extended period of time, you get some pretty high heat. I know my mag trainer can easily hit 200 after an hour on medium or high resistance.

    Remember wattage is a measurement of energy, heat is a by product of energy.....pedaling a resistance device has to disapate that heat and energy somewhere, so it does that into the trainer and heat vents/coils.
