We will have cut off times for each distance. These cut off times will ensure participants are able to finish in daylight (sunset is 18:17) 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

Yes, small bags can be left with our team at the start of the event. Your small bags will be taken by us to the finish location, for you to collect at the end of your run. There is no charge for this service.

You will be given a bag tag as part of your race pack, which is collected on arrival at the event. The bag tag should be secured to your bag in a prominent position.

No hard cases please.

The second Queen of the Suburbs Ultra will be on Sunday 24 May 2026. Start times will be confirmed but likely to be between 7am and 11am.

There is no race pack to be received. All elements for the event are collected at registration, on the day of the event.

Start times/waves will be communicated in early March 2025.

Entries close on 1 March 2025, if not sold out before. 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.
