We have partnered with Let’s Do This to take event entry bookings. When you enter an Ultra Series event, your entry information and payment is processed by Let’s Do This and passed securely to us. Your bank statement will show Let’s Do This against your event entry and you will receive a booking confirmation email from Let’s Do This, in addition to your usual entry confirmation email from us. All pre event advice and information will arrive in your inbox from Ultra London.

If you need to make changes to any of your contact details please contact us here and we can sort that for you.

Yes you can, subject to the event cut-off times (see FAQ Does the Event Have Cut-Off Times). When you register, please state a realistic completion time, including time for eating, drinking and toilet stops. We will place you in the appropriate wave for your predicted time. You can alter your estimated completion time up to 6 weeks before the event by emailing us here, or on event day at the registration point. The required speeds for the shorter distances are slower than the longer distances, and should be achievable for most walkers. Start Waves/Times You will be allocated a start wave/time based on your estimated completion time, with those moving at a slower pace starting in earlier waves so that they have the longest possible time to reach the cut off points. Start wave times are allocated in the weeks before the event. If you’re concerned about whether you will get round in time based on your allocated start time please contact us here in advance of the event day.

Yes (but they’re not overly tough!). The required speeds for the shorter distances are slower than the longer distances, and should be achievable for most walkers. Please note: locations and times may be subject to change. ULTRA 55 There is a required completion time of 18.00hrs in Richmond. For those starting in the first wave at 07.00hrs this means an average speed of approx. 12mins/km (19mins/mile) or faster. The first cut off time will be at the second checkpoint at Upper Norwood at 13.00hrs (regardless of your start wave time). A second cut off point is at the entrance to Richmond Park at 17.00hrs for any participant who has not yet passed this point. If you have not passed the cut-off points by the times specified above we’re afraid you will not be permitted to continue. TRAIL 25 There is a required completion time of 18.00hrs in Richmond.

Start Waves/Times You will be allocated a start wave/time based on your estimated completion time, with those moving at a slower pace starting in earlier waves so that they have the longest possible time to reach the cut off points. All participants will receive an email with their personal start time. If you do not receive this email a week before the event, please contact us here. If you’re concerned about whether you will get round in time based on your allocated start time please contact us here in advance of the event day.

As with all ultra running events it is important that you wear appropriate kit - and test your kit out on a long run/walk prior to the event. You should be prepared for all likely weather conditions, taking into account weather forecasts for London in the lead up to the event date. Consider the following: Shoes - comfort/cushioning, lightweight, adequate grip for multi-terrain Socks and underwear - comfort, able to wick away moisture Gloves Legs & upper body - consider the potential of changing temperatures and the potential for wind and rain. Race pack & hydration vest - comfort is key but also consider how much you want to carry with you, and ease of access whilst on the run. And remember to train with the gear you plan to race in.

We love dogs and hope that in future years we will allow them to participate in aspects of the event (accompanied obviously). However this year we are limiting the event to just those on two legs only.

ULTRA 55 will start in Woolwich. TRAIL 25 will start at Upper Norwood. All locations are well-connected with good rail, bus and Tube links. Exact venue locations will be shared well before the event date and included in the event guide.

ULTRA 55 will finish in Richmond upon Thames TRAIL 25 will finish in Richmond upon Thames Finish Location: Richmond Athletic Ground, Kew Foot Rd, Richmond, TW9 2SS. Richmond railway station is approx. a 500 metres walk from the finish. Bus routes that serve the Finish can be found here.

The ULTRA LONDON course is on or very close to the Capital Ring path. Being an urban ultra event you can expect the terrain to be a mixture of footpaths, parks, woodland trails, canal paths and disused railway lines. There are also steps in places. Dependent on weather conditions parts of the route may be muddy. Whilst it is not mountainous, there are hills in places that will provide a challenge for participants.

Yes. There are a number of road crossings on the route, some quiet and some will be on busier roads. It is the responsibility of all participants to ensure they travel along footpaths and not on roads, and that they cross roads at suitable and designated road crossing points. Participants must leave gates as they find them (i.e. opened or closed). The event is on public footpaths and other footpath users will be present. All participants must be aware of other footpath users, be courteous and polite at all times. Please avoid running/walking abreast on narrow footpaths.

Yes, there will be event-specific directional signs and confidence markers throughouth the course. At registration and in the briefing before the race participants will be shown the course markers. Due to the nature of the route, certain parts are somewhat complex to navigate and runners are advised to moderate their speed at these points to ensure the correct path is taken. A sports GPS navigation device is reccomended if you have one - GPX route files will be released closer to the event date. More detailed course notes will be published closer to the event date.

If you are having trouble importing the GPX route file into an app on your Phone, please refer to the help/FAQ section in your chosen app for help. Generally GPX file import uses the 'Copy to Explore' (iOS), or 'Open with Explore' (Android) method to open in your chosen app on a mobile device once the file is downloaded. iPhone users please note - the "share" function and "Copy to Explore" may not be available to users after the release of iOS 13. If you do not see "Copy to Explore" contact Apple Support or use another method to import your GPX file. If you are having issues on a Garmin device please refer to the instructions on importing a GPX file on a Phone here.

For participants, we strongly advise using public transport to access the start and finish locations. There is no event parking available at the start locations. For spectators, public transport is also recommended.

The start locations will have toilets and changing facilities available. We recommend that participants arrive with a full supply of drinking water. At the finish there will be toilets and drinks available. A bag drop and transfer service will be provided from the events starts to the finish. Please note that the baggage transport will leave the start locations only when the last participants have started at that location.

No pacers are allowed in this event. You are allowed to run with friends (who have also entered the event).

Yes, participants may receive support from friends and family along the course. Naturally this support cannot extend to assisting the participant to travel along the course.

Yes, participants can give one bag to the race organiser at the start to be taken to the finish. This bag should be as small as possible. No suitcases please. Please note that the baggage vehicle will leave the start only when the last participant has started. Also note that once bags have been taken to the finish they cannot be transported elsewhere and must be collected at the finish.

A map and/or course notes are recommended. Whilst there will be event-specific directional signs and confidence markers throughouth the course, due to the nature of the route, certain parts are somewhat complex to navigate and runners are advised to moderate their speed at these points to ensure the correct path is taken. A sports GPS navigation device is recommended if you have one - GPX route files and more detailed course notes can be downloaded on the /route/ page before the event.

All finishers will receive an exclusive medal and tee-shirt. The first man and woman in each distance will receive a commemorative trophy.

If you need to drop out during the race it is ultimately your responsibility to notify event control (via phoning the event control number or notifying event staff at the checkpoints) of your decision to retire from the event. If you have a bag to collect, you will need to make your way back to the finish line. We will try to help where we can although please note that public transport might be the most suitable option. Except in an emergency or where you cannot continue due to injury or ill health, please make your way to the next check point and inform the event staff at the check point that you intend to drop out. This is important so that we can account for all runners in the event. If you cannot make it to the check point, you must call the event control (phone number will be on your race number bib) to notify them of your location and of your intentions for onward travel (i.e. if you are planning to make your way to the finish). In the unlikely event of an emergency situation call the emergency services first and then call event control. Participants who retire will not receive a finishers medal or t-shirt.

Medical support is provided on course and at the finish. However please note that due to the nature of the event participants should recognise the physical challenge and should train and prepare adequately. If you have not been able to prepare properly please do not take part. For much of the route participants are expected to be self-supported. ​If you have a problem that requires medical attention but you can make your way to the next checkpoint please do so. If you (or another participant you are attending to) require medical assistance and are unable to reach the next checkpoint please call Event Control - this number will be on your race number bib. In the unlikely event that emergency medical attention is required please call the emergency services on 999 in the first instance and then call Event Control.

The Event Control number will be printed on your race number. Participants will be advised to save this number into their phone at registration.
