The Westerley Cycling Club presents an exciting time trial challenge at Hillingdon Cycle Circuit. Cyclists can choose between two distinct events, each designed for different levels of equipment and racing conditions. For those seeking the ultimate aerodynamic advantage, the Time Trial Bike Event offers a 25-mile course completed over 40 laps on a car-free outdoor circuit. Participants are encouraged to utilize any time trial or triathlon bikes equipped with full aero helmets and deep section wheels, including disc wheels. The event is strictly non-drafting, ensuring fair competition while prioritizing safety. Alternatively, the Road Bike Event caters to riders who prefer conventional road bikes without aerodynamic enhancements. This option allows for mountain bikes as well but prohibits the use of time trial bars or aero clip-on bars, pointy helmets, and deep wheels exceeding 60mm depth. Like its counterpart, this event is also non-drafting. Both events are open to adults at £10 each, with discounts available for Westerley Cycling Club members (£5) and juniors (£5). Cyclists must independently track their laps; the course requires a total of 40 laps covering exactly 25 miles. The event promises an exhilarating experience on this well-maintained circuit known for its smooth surface and controlled environment. Join us at Hillingdon Cycle Circuit to test your speed and endurance against some of the best cyclists in the region, all while enjoying the thrill of solo racing under clear skies.
