  • When will I know my start time?
    Start times/waves will be communicated on Tuesday 19 March. Entries close on Monday 18 March and the final list of starts will be arranged immediately after. However, you can get a good idea of your start time by following the following general rules: The starts are arranged slow to fast. The start times are 07:15 - 08:30 (Ultra 50km) and 10:00 - 10:50 (Trail 25km). So you will be able to estimate your start time based on how quick your estimated finish time is. If you have entered the same estimated completion time as a friend you will be placed in the same wave.
  • Can I change my start time?
    The start times are arranged based on your estimated completion time. This is arranged so all participants have the best opportunity to finish the event before the cut off time, and don't get the finish too early. Start groups will be small 20-30 maximum, every 10 minutes. The Ultra 50km start times are between 07:15 and 08:30. The Trail 25km start times are between 10:00 and 10:50. The start groups will be in slow to fast order, with the later start times being for the quicker runners. Once the start times are published, you will not be able to change your start time. You can change your estimated completion time before 1 March 2024, either by altering your registration online or by emailing us at No changes to your estimated completion time are possible after 1 March 2024.
  • Are there checkpoints/water stations?
    Yes, there will be checkpoints/water stations available on both 25km and 50km routes. Checkpoints will have water and some snacks. Trail 25km route has 2 Checkpoints - both at the Fox Inn, Hanwell, Green Lane, London, W7 2PJ - What3Words: ///fades.swept.rings Ultra 50km route has 5 Checkpoints: Checkpoint 1 - Fox Inn, Hanwell (as above) Checkpoint 2 - Northala Fields, Westway Close, Northolt, London, UB5 6UR - W3W: ///market.metro.fines Checkpoint 3 - Horsenden Hill, Horsenden Lane N, Perival, UB6 7PQ - W3W: ///still.pots.poster Checkpoint 4 - Pitshanger Park, London, W5 1LS - W3W: ///oddly.figure.closet Checkpoint 5 - Fox Inn, Hanwell (as above)
  • Do I have to stop at the Checkpoints?
    No, you do NOT have to stop at the Checkpoints. Checkpoint 1 and 2 on the Trail 25km route and Checkpoints 1 and 5 on the Ultra 50km route are all in the same location - the Fox Inn, Hanwell. This Checkpoint is 30m off the route and is non mandatory. You do not have to stop here. The other Checkpoints on the Ultra 50km are also non mandatory to stop at, but you will be running directly past them. Please do show (or call out) your bib number to the Checkpoint team as you go through. The Checkpoint teams will be tracking the numbers of runners as they come through, either by noting their numbers or by scanning the bar code on the bib number.
  • Are there cut off times?
    We will have cut off times for each distance. These cut off times will ensure participants are able to finish in daylight (sunset is 18:19) and ensure our medic and volunteer team have defined hours of work. There are cut off times at Checkpoint 2 (Trail 25km only) and at Checkpoint 3 (Ultra 50km only), as well as at the Finish. Please make sure you include an accurate estimated completion time for your challenge in your registration, that way we'll be able to ensure you are in the appropriate wave for your running/walking speed and you'll have the best opportunity to complete the challenge within the allotted time. Trail 25km cut off time: 17:00 at Fox Inn (Checkpoint 2). Retiring participants at this point, who miss the cut off time will be directed to local bus services, in order to get to the finish (Ealing Broadway). Ultra 50km cut off time: 13:00 at Horsenden Hill (Checkpoint 3). Retiring participants who miss the cut off time will be directed to Perivale Tube station, in order to get to the finish (Ealing Broadway). A participant, who has started in the appropriate start wave (between 07:15 and 08:30) is unlikely to be able to get to the finish before the finish line cut off time. The Finish line closes at 18:00
  • How do I calculate my estimated completion time?
    The estimated completion time is important as it ensures we can place participants in the appropriate wave starts. If you have never done the distance before it may be hard to estimate an accurate estimated completion time, but we'd recommend considering the following: Ultra 50k: You should NOT simply take your 10k PB and multiply by 5! The course is off road/trail and the terrain will vary, there will be hills, you will stop at checkpoints, you will need to take on food as well as water, you will need to cross roads and at times wait for pedestrian lights etc. You may also be slower than your normal run or recent race due to the distance. So, all the above will impact your finish time. The best way to estimate your estimated completion time is on a training run (of say, 25km) double your time and then add some more on for slower running, stops at checkpoints etc. Your estimated completion time may also be impacted by your strategy - you may want to run it with friends, or walk the middle 10km etc. So all of the above will need to be taken into account, but we do recommend you err on the side of caution for your estimated completion time, especially if it your first ultramarathon.
  • Can I volunteer?
    Yes, absolutely! The event will need lots of volunteers and we are really appreciate everyone who gives their time to help us put the event on. There are some great volunteer roles available, from helping with registration to helping keep the runners going at checkpoints and awarding medals.

  • What are the route conditions like?
    The route is on mixed terrain: footpaths, tarmac, gravel, grass, mud. Some sections of the route may be liable to flooding/muddy conditions. In particular, the Ultra 50km route (just after the Split point) is particularly wet, We will update you all on course conditions in the immediate build up to the event via social media, so please follow us on Instagram, Twitter and Facebook (links to our accounts on our home page).
  • Can I change my start time?
    The start times will be published Tuesday 19 March. You are able to request a start time change before Thursday 21 March (midday). However, start times will not be changed if there is a risk of missing the cut off time or finishing the event too early. We will keep faster runners to the later waves and slower runners to the earlier waves.
