Keep it rolling
When there’s really no chance to cycle outside, the best alternative to the real thing is a roller or turbo trainer. They are not only good solutions for autumn and winter or bad weather in general, but also for your warm up before a race. What’s more, they may help you to achieve a new performance level. Which kind of trainer you prefer is completely up to you: a wheel-on turbo trainer, a roller or a bicycle home trainer with direct drive, the latter offering the probably most realistic riding feeling.
