Jekyll & Hyde Park Halloween Duathlon

15 Oct 17

A duathlon in the heart of central London.

The entire race is held within Hyde Park and Kensington Gardens.

The first run is within Hyde Park (1 lap; 4.2km). The bike is 9 laps of South Carriage Drive (20.8km) - don't be fooled, it's not flat but it should be fast and the road surface is good. You finish running 2 laps within Hyde Park (7.6km). All distances are approximate.

Due to a clash with the changing of the Queen's Life Guard, there is a strict bike cut-off of 9:30 am. If you have not started your final lap by 9:15 am you may be withdrawn from the race.

Start, finish, transition and registration will be at the southeast corner of the park where South Carriage Drive approaches Hyde Park Corner.

Withdrawal / number transfer policy: if you are unable to race you may transfer your number to another person or obtain a refund (minus an admin fee), up to midnight on Monday 2nd October. THIS MUST BE AGREED with the race director. Refunds will only be processed where the place can be transferred to another person. To request a refund or to make a transfer, email

Transfer of numbers without approval of the race director can be dangerous if emergency services cannot reach the correct next of kin and also unfair as it can distort the results. Any unapproved number swaps will result in disqualification of the receiver of the number and a ban from all future Serpentine events for both parties.

The event is open to triathletes of all abilities. If you have a specific need please contact the organiser by emailing  to discuss your requirements.

SERPENTINE MEMBERS MUST CONTACT THE RACE DIRECTOR BEFORE ENTERING. Entry to this race for Serpentine Running Club members is ONLY open to those who've received permission to enter from the race director. Anyone who enters without seeking permission first will be withdrawn from the race and charged an admin fee.
