The Performance Improvement Guarantee (P.I.G.)

Unlock Your Race Potential with a CompuTrainer.
Guaranteed to Increase Your Bike Speed by 2 MPH.


The regular use of a CompuTrainer will increase your bike speed by 2 to 4 MPH. This is a bold statement backed by the experiences of over 25,000 triathletes and cyclists of all ages and ability levels over a 20 year period. It is such a routine result that we unequivocally guarantee it.

If your bike speed does not increase by at least 2 MPH over a 5 month period of regular use, you can return the CompuTrainer for a full refund of the purchase price.

CompuTrainer's Performance Improvement Guarantee
Terms and Conditions

The original purchaser of a CompuTrainer may return it within 12 months of the purchase date for a refund of the purchase price if his/her cycling power (watts) and speed have not increased by 2 MPH or more after training on it for a minimum of 3 days per week, a minimum of one hour per day, for 5 consecutive months. The following conditions apply to this Guarantee:

1) The 5-month period begins as soon as the purchaser starts using the CompuTrainer. The date of first use must be within 6 months of the purchase date. The 5-month period ends 22 weeks from the date of first use.

2) The Racelog option within the 3D software “Options Menu” must be activated and the actual racelog.csv (which lists the dates and actual training times for the 22 weeks use on the CompuTrainer) must be provided to us.

3) The beginning power and speed used as the basis for the determination of the percentage increases are to be determined within 3 days of the date of first use. Power and speed are defined as the average speed and average watts recorded on the standard CompuTrainer 10K Time Trial course, which can be downloaded from the Free Courses page. The beginning 10k time trial performance must be saved in the CompuTrainer 3D software to substantiate the initial average power and average speed results.

4) At approximately one month intervals four additional 10K time trials are to be saved (recorded) using CompuTrainer 3D as evidence of the continuous 5 month training program with the last time trial recorded at the end of the 5 month period.

5) It is assumed that a CompuTrainer returned under this Guarantee will show signs of normal use. An adjustment in the refund amount of the original purchase price, excluding freight, will be made for damages which occur during return transportation, for missing parts, and for water damage.


Please feel free to contact us for clarifications or any questions you may have regarding the Performance Improvement Guarantee. It is a major factor in the CompuTrainer product and we are proud of the beneficial impact it has had on the training routines of thousands of athletes.
