Westerley Cycling Club presents an exciting series of time trial events at Hillingdon Cycle Circuit, offering cyclists two distinct race categories: Time Trial Bike Event and Road Bike Event. Both races take place on a car-free outdoor circuit that stretches 10.35 miles over the course of 11 laps. For those looking to push their limits with high-performance equipment, the Time Trial Bike Event welcomes riders to use any type of bike including time trial or triathlon bikes, full aero helmets, and deep section wheels such as disc wheels. The event is non-drafting, ensuring fairness and safety on the track while providing an opportunity for cyclists to showcase their aerodynamic setups. The Road Bike Event caters to those who prefer traditional road racing without the use of advanced aerodynamics. Cyclists can participate with a mountain bike or standard road bike but are restricted from using clip-on bars, time trial/triathlon handlebars, pointy aero helmets, and wheels deeper than 60mm. Entrance fees vary: adults pay £10.00, Westerley CC members enjoy a discounted rate of £5.00, while juniors can join for just £5.00 in both categories. All participants must adhere to the current Cycling Time Trials guidance regarding safety measures and race protocols to ensure a secure environment. The event promises an exhilarating challenge set against the backdrop of Hillingdon Cycle Circuit's smooth asphalt surface, offering cyclists the chance to test their speed and endurance on this well-maintained track. With no traffic interference, riders can focus entirely on pushing themselves while enjoying the camaraderie among fellow enthusiasts.
