Please note the following changes for the event and please read the codes of conduct below.

1. The first change you will notice is the start time. Rather than a single start time for all runners, we are operating a pre-booking system with start times available in 3-minute slots. People will be allocated a place on the start line according to their anticipated finish time, with the fastest runner lining up on the front of the start line.
2. Please arrive ready to run. There are no changing facilities and no facilities for left baggage – this is in line with UKA Guidelines.
3. A sterile area will be in force around the start line with strictly no access to anybody other than participants and race officials. Once you enter this area you will not be able to leave until your race begins. NO SPECTATORS WILL BE ALLOWED WITHIN THIS STERILE AREA.
4. Again, in line with UKA Guidelines, water, in sealed bottles, will be available at the finish and you will be required to collect it yourself from an unmanned water table – hand sanitiser and gloves will be available for you to use. There will not be a water station on the course. Please dispose of the bottles and other litter in the bins provided.
5. Again, in line with UKA Guidelines, no results, race prizes or awards will be available on the day. Results will be uploaded immediately to our website and emailed to participants. Race and age group winners will receive a trophy in the post after the event. Medals will be available to be collected at the event.
6. There will be toilet facilities at the start / finish area and these will be sanitised regularly. Please play your part by washing your hands thoroughly and using hand sanitiser before and after use.
7. Hand sanitiser will be available – please use it regularly.
8. You must maintain social distancing at all times – before, during and after the race. When overtaking another runner please be mindful of the space available.
9. Spectators are not encouraged to attend – but if they must do so, they should not congregate around the race start or finish areas.
10. Once you finish your race please continue to walk through the finish funnel and return direct to your vehicle – do not wait for friends or family.
11. Please read the Participants and Spectators Code of Conduct - Please observe the ‘Rule of 6’ and do not gather in large groups to discuss the race or take team photos.

Organiser's Description

A firm favourite amongst endurance runners, this event on the secure, traffic-free, undulating, tarmac route at the Redbridge Cycle Centre in East London, sees runners covering multiple laps of the 2k cycle circuit, finishing on what will, hopefully, be a balmy Summer evening.

The event features a choice of three distances from half marathon through to a 50k ultra distance, with start times varying according to the distance you select. If you aim high and select the 50k option, you can always step down to a shorter distance after you have started.

The race is perfect for runners of all abilities, from those looking to complete their first ultra or marathon distance, to seasoned long distance runners. The races have generous cut off times, with the circuit and event not needing to be cleared until 9pm. So, if you are looking for something a little bit different to the big city, mass participation marathons, then this could be the event for you!

Course Details

This race uses the tarmac circuit at the Cycle Centre and runners complete multiple laps. Ultra distance runners will complete just over 24 laps; the marathon consists of just over 20 laps and the half marathon just over 10 laps.

The surface is all tarmac and so your favourite running shoes will be just fine.

Each 2k lap will see you cover two uphill climbs and one exhilarating descent – the hills are not significantly steep but they will challenge your endurance.

Because each lap is relatively short at 2k, the races are perfect for those looking to complete the distance for the first time – you’re never far from the finish line and for assistance should you need it.

Runners will be offered a variety of food and snacks plus hot and cold drinks. A water/aid station will also be located at the finish. Although we will ensure our water stations are well supplied, athletes are encouraged to bring their own nutrition and carry their own water bottles. We are happy to refill water bottles for you.

Changing and Shower Facilities: There are no changing rooms or showers at this event.


As you cross the finish line please make sure you cross over the Chip Timing mat which will automatically record your official time against your race number.

Any runners wearing a bum bag around the course must be careful not to apply pressure to the timing chip on the reverse of your race number. This can cause a problem with the signals from the chip and may affect your race time. This also applies when starting/stopping your watch as you cross the line – please wait until you have crossed the mats before activating or deactivating your watch.

Signal Permitting- Live results will be available on during the event and a full set will be posted online shortly after the event has finished. All athletes who provide us with a legible email address will also be emailed the final results on the next working day following the event. If you are missing from the results or need to report an issue, please email us at
