Getting there

As London is so busy and because Serpentine run and tri club support a healthier lifestyle, reducing our carbon footprint and fighting climate change.

They recommend saving time, money and improving fitness as well as helping the environment by choosing to walk, cycle or use public transport and if you must you a car, try sharing.

Cycling - It's a fantastic way to warm up your legs prior to the race. Please remember that cycling is not allowed on many of Hyde Park's footpaths - when making your way to and from the race please respect this and don't risk creating ill-feeling with the park authorities and users. This might prevent this event from being run in the future.

Parking - There is limited parking in the area - parking is available at the Diana Fountain and the Triangle Car Park, both off West Carriage Drive, and there are spaces on West Carriage Drive itself. Please note that parking is not free after 8:30 am. Underground Parking is available at the Park Lane Car Park.

Please note there is no race day entry to this event, all entries must be made in advance.

The Course

First Leg (Run):

Run 1 lap of the Serpentine on tarmac paths - 4.2km.

Second Leg (Bike):

Cycle 8 laps of South Carriage Drive (roads closed to traffic). Don't be fooled, it's not flat but it should be fast and the road surface is good. Dead turns at both ends - 20.8km.

Due to clash with the changing of the Queen's Life Guard, there is a strict bike cut-off of 9:30am. If you have not started your final lap by 9:25am, you may be withdrawn from the race.

Organisers have found in the past that every year a few competitors complete the wrong number of laps. It is surprisingly difficult to count to eight as you get tired. A handy tip is to attach 8 small pieces of tape, one for each lap, to your bike frame. Peel one off at the end of each lap and when you have one left you know you are on your last lap.

Third Leg (Run):

Run 2 laps of the Serpentine on tarmac paths - 7.6km.
