Vision in triathlon: The challenges facing cyclists

Triathlon is one of the fastest growing sports in the UK. The three-sports-in one format appeals to many. It also throws up some interesting issues for the optical practitioner who has triathlete clients. In the second article in this series, we look at the visual demands of the cycling discipline.

To understand the visual demands of cycling in triathlon, it is necessary to understand how cycling as part of a triathlon may differ from regular cycling. There are two main types of bicycles commonly seen on UK roads: those with flat handlebars (hybrid or mountain bikes) and those with dropped handlebars (road or racing bikes). The first category allows the rider an upright, vertical position and thus a head posture similar to that of walking. The second category requires the rider to lean forward more and thus requires the head to be tilted back slightly.
