The Westerley Cycling Club presents a series of time trial events at Hillingdon Cycle Circuit, offering cyclists two distinct racing options on an exclusive car-free outdoor track spanning 10.35 miles (11 laps). For those seeking the ultimate aerodynamic advantage and willing to invest in top-tier equipment, the Time Trial Bike Event welcomes riders with full aero helmets, deep-section wheels including disc wheels, and time trial/triathlon bikes. Participants must adhere strictly to non-drafting rules for safety and fairness. The entry fee is £10 for adults, while Westerley CC members and juniors pay just £5. Alternatively, the Road Bike Event caters to riders using standard road or mountain bikes without aero bars, triathlon frames, disc wheels, or deep-section rims exceeding 60mm depth. As with all events at Hillingdon Cycle Circuit, non-drafting is enforced throughout the race for competitive integrity and rider safety. The entry cost remains consistent: £10 for adults and just £5 for Westerley CC members and juniors. Both races are conducted in accordance with current Cycling Time Trials guidelines to ensure a safe and secure environment. Competitors must independently monitor their lap count, as each event consists of 11 laps covering the full distance of 10.35 miles. Join us at Hillingdon Cycle Circuit for an exhilarating challenge that caters to all levels of cyclists, from seasoned professionals to enthusiastic amateurs looking to test their mettle on this iconic track.

About Hillingdon

Hillingdon is an area of Uxbridge within the London Borough of Hillingdon, centred 14.2 miles (22.8 km) west of Charing Cross. It was an ancient parish in Middlesex that included the market town of Uxbridge.
