About registration
Very quickly! In previous years, all public entries have sold out within just a few hours of release. To avoid missing out, we strongly recommend joining our mailing list for early access before entries go live to the public. Sign up here
Public entries open in early August via our entry portal provider Let’sDoThis. However, if you're on our mailing list, you’ll get early access to registration — including the chance to secure your place at the lowest early bird prices. Entries are sold in tiered pricing bands, so the sooner you sign up, the better the value. Once a tier sells out, prices move up to the next. If entries sell out to the mailing list, there may be no Public sale.
If you selected ‘Refund Protect’ when entering, you're covered under their terms — these override the standard event policy. You’ll need to follow their claims process directly. If you didn’t purchase Refund Protect, you may still be eligible for a partial refund or can transfer your entry to another person through the official process. Please note: Bib swapping is strictly prohibited. Anyone found running under someone else’s name will be removed from the results and will be barred from future events. For full details, please read our Terms & conditions.
We don’t operate a waitlist for the TTP Cambridge Half Marathon. However, you may still be able to secure a place by running for one of our official charity partners. Check out our charity entry options by visiting our Charity page.
It’s easy to run for a good cause! Our official charity partners often have entries available before and after public entries sell out.

About the race
Your race pack includes: Your race bib with the timing chip pre-attached (please don’t bend it) A bag drop tag for event-day storage You can choose to have your pack posted when you enter, or collect it in person from the event site on Friday or Saturday before race day. Please note: We’re unable to post race packs to non-UK addresses, so international entrants will need to collect theirs in person.
The Cambridge Half Marathon route is a UKA-certified 13.1-mile course, designed for speed and ideal for PB chasers. It’s famously flat, with less than 320ft of elevation gain across the entire course. The race takes place on a mix of closed and partially closed roads, guiding runners through the iconic grounds of St John’s, Trinity, King’s, and Jesus Colleges – offering a truly scenic and memorable run through the heart of historic Cambridge.
Both the start and finish lines are located on Victoria Avenue. Runners will access the start and finish pens via the event site on Midsummer Common, with easy, well-signed loading areas for a smooth race-day experience.
The race will begin in seeded waves, with the fastest runners setting off first. This helps ensure a smooth and safe start for all participants. You are assigned to your starting wave based on the estimated finish time you provide when you enter the event. Please note: the full start process can take up to 45 minutes from the first wave to the last. If you’re a VIP athlete, you’ll have access to a dedicated start channel for a more streamlined experience.
Yes — there will be a bag drop tent located on the event site, available for all registered runners. Please bring a zipped bag no larger than 40 x 20 x 25cm (roughly cabin bag size) containing only the items you wish to store during the race.
Yes — there will be five drinks stations positioned along the route, plus water available at the finish line to help you rehydrate. We’ll confirm the exact locations and any additional items (such as nutrition or energy drinks) in the coming weeks. You’ll also find water bottle refill points in the event village area, so you can top up before or after your run.
Yes — toilets will be located at the event site and at each drinks station along the course. Each toilet area will include women-only facilities, and all toilets on the course designated for women will be stocked with free sanitary products.
Once you cross the finish line, it’s time to celebrate! You’ll receive your finisher’s medal and a finisher bag containing your premium event t-shirt (unless you opted to donate a tree instead). After collecting your goodies, head to the massage tent where our team of therapists will be on hand to help kick-start your recovery with a well-earned post-race massage.
All runners have 3 hours and 30 minutes to complete the course, measured from the moment you cross the start line. There will be a midpoint cut-off on the route. If you're behind the required pace at this stage, our team may ask you to move to the pavement for safety reasons. Please note: Runners behind the cut-off time will not be able to access the college sections in the later part of the course.
