Yes — it's important that your estimated time is correct, as your start time and wave are based on it.

The locations of the sites are shown below.

The first bus leaves each site at approximately 07:00, with the last bus at approximately 08:30 (08:00 from St Ives and Longstanton, due to the longer journey to the event village). Drivers may wait until the bus is full before leaving.

The last buses leave the event site at 15:00; after this time, you can still use your ticket on the standard Park & Ride service.

All buses collect from the same point where you were dropped off, except for the Madingley Road bus, which collects from the opposite side of the road.

The last bus from the event stops leaves by 15:00; after this, you can use your ticket on the standard service. Return point locations are listed below.

The event village and start is on Midsummer Common, CB5 8DJ (What3Words: ///middle.energy.handed).

If you live locally or are staying nearby, please walk or cycle to the event to help reduce traffic in the area. There is a secure bike park on-site, open throughout the event.

For those travelling by car, we offer a Park and Ride service; each bus drops you a short walk from the event village.

All participants need to be on the event site before the race starts, to ensure a smooth arrival.

The Event Village opens from 07:00, and the race starts at 09:30. We recommend arriving before the race starts, to ensure a smooth pre-race arrival.

In your Race Pack you will be given a tag to attach to your bag. If you have lost your bag tag, the team will have spares. Please keep your bag as small as possible — think airport hand luggage.

The large marquee, which opens at 08:00, is marked out in athlete number order. Please ensure your bag is ready to hand over, with label attached and no loose items, before you arrive, to reduce queues.

Please keep your race number on after you finish, as the Bag Storage team will need to match it against the bag you are collecting.

There will be a secure bike storage compound on-site during the event, including on-site security (What3Words: ///dwell.exam.nets).

Bike storage will be open from 07:30 and will close around 15:00. On arrival, you will be asked to write your race number on a sticker to attach to your bike. When you return, you will need to show your race number to match it against your bike.

Please do not lock your bike to the fence or racking.

Friday: 12:00–18:00, and Saturday: 10:00–16:00, located inside the Race Pack Collection Marquee (What3Words: ///buns.juror.crisp).

Sunday: 07:00–14:00, located outside the VIP Marquee (What3Words: ///sketch.thigh.lobby).

You will be sent an email detailing your individual race number and "To The Start" time approximately 3 weeks before the event. If you have not received any emails from us in the lead-up to the event, please get in touch.

Please read the Race Information, which will have details of important timings on race day, along with the most up-to-date map of the event site.

There will be announcements from the main stage as each start group is called into its Start Area, plus notifications on the big screen in front of the Start Gates.

There will be 3 guided group warm-ups from the Main Stage in the Event Village, at approximately 09:00, 09:30 and 09:40, but these may be subject to change.

Please listen for announcements from our commentary team.

If you'd rather warm up on your own, you can run along the river path away from the Event Village.

If you have a welfare issue — including a lost or found child, or an adult at risk — please speak to any Volunteer or member of staff, or head to the Enquiries Marquee on Midsummer Common, located in front of the VIP Marquee.

There will be pacers on the course, identifiable by a pacer t-shirt and, in most cases, a flag. They will be pacing the following times:

Under England Athletics rules, you cannot wear headphones during the race, in the interest of athlete safety.

The only exception is bone-conducting headphones, which do not go in or cover the ears.

We are instructed to disqualify any athlete who breaks this rule.

Yes — there will be a specialist event medical company on-site for the duration of the event, with a team of medical practitioners and support vehicles around the course able to travel to any incident and transfer directly to hospital, should the need arise.

If, before, during or after the event, you feel you require medical care, please do not hesitate to contact an event marshal. Please note that if you require medical help you will need to stay in one place — if you decide to continue moving, we will not be able to assist.

There is also a public first aid unit in the Event Village, accessible from beside the stage.

If you would like to be considered as a Pacer for the 2027 event, please complete our Pacer Form before 30 September 2026. No applications can be accepted after this date.

All applicants will be notified by 30 November 2026.

We receive a lot of requests to join the pacing team, so please don't rely on this if you definitely want to run the event. If you are chosen as a pacer, your purchased place will be refunded to you or deferred.
