Improve your bike performance by 10% in five months on this month’s competition prize, the CompuTrainer, worth £1,200.

Widely recognised among pro and age-group athletes as the number one indoor bike trainer in the world, one lucky 220 reader could be about to find that out for themselves if they’re plucked from the hat of fortune this issue.

So widely regarded is the CompuTrainer that many of the top triathletes ask to be sponsored by CompuTrainer to help them get to, or stay at the top of, their profession. CompuTrainer ambassadors include triple Xterra World Champion Julie Dibens, multiple Ironman champions Bella and Stephen Bayliss, former ITU short- and long-course champion Leanda Cave, and Ironman UK winner “Fearless” Phil Graves. Not to mention the fact that at this year’s Ironman World Championships in Hawaii, six of the top 10 men and women regularly rode their CompuTrainer in training.

As well as boosting your performance, the CompuTrainer turbo trainer (which you connect to your PC) also offers: real course videos so that you can prepare for your next race on the actual course; unmatched accuracy in measuring power; solid construction for years of breakage-free training; a five-month 100% money-back guarantee if after using the product your performance doesn’t improve (as well as another 10% return on top, exclusive to the 220 comp winner); unrivalled customer support; free coaching software; and free 20-week Performance Improvement Guarantee training programme.
