Enter now to take part in a unique event that will take you on a tour of the historic Cambridge boundary
The Boundary Run is a marathon (~26.2 miles) and half-marathon (~13.1 miles) race that takes participants around the boundaries of Cambridge. The course traverses roads, footpaths and trails, and incorporates some beautiful and not-often-seen areas of the city. It’s a laid back event with a friendly and pressure-free atmosphere.
Both the full- and half-marathon courses are about 30% off-road, and there are several reasonably sized hills on the course – significant enough to surprise those who are used to the flat terrain of Cambridge. This is a challenging but fun and rewarding course.

Any queries can be made here. Please read our FAQ’s below before submitting a query.
How do I enter?
Please go to our entry page on the website. Entries close 3 weeks prior to the event (Sunday 9th February)
Is there a warm place at the start/finish?
The start of both races is the University Sports Centre. The finish of the half is Coldham’s Common which can get chilly (although there will be coaches to transport you back to the Sports Centre). There is parking and toilets available at the Abbey Leisure Centre by Coldham’s Common. The full marathon finishes back at the Sports Centre.
Where should I put my bag?
You can drop your bag at the start and we will keep it in the Sports Centre or transport it to Coldham’s Common dependent on whether you’re running the full or the half. Any bags left at Coldham’s Common will be returned to the Sports Centre in the case that you decide to run the full instead of the half. We would like to stress that we can’t be responsible for valuables etc. in your bags so we highly recommend making sure you leave these somewhere safe.
Do I need anything for the day?
We advise you to carry a mobile phone as well as a route map to reduce the chance of getting lost. Closer to race day, we will send a GPX file of the course so you can track your progress on your mobile phone. Printed maps will also be available at registration.
Will the course be marked?
We will mark the course with flour, streamers and there will be regularly spaced marshalls. Following the course should be straightforward but we suggest you acquaint yourself with the route beforehand and perhaps keep a map on your phone in the event that you find yourself in the wrong place!
Are the roads closed?
The roads are not closed. There are a couple of road crossings where traffic is fast-moving, we therefore request that all participants cross roads as safely as possible, whilst retaining a clear awareness of traffic. We will place marshals at road crossings, but ultimately it is your responsibility to ensure that you cross in a sensible manner.
I don’t know if I’m fast enough?
We’re a very relaxed event here at Boundary Run, but it is organised by students who have a very busy schedule. We recommend that if you want to have an official time, that you finish within 7 hours for the full marathon and 3.5 hours for the half marathon. However, you are more than welcome to start and follow the course round if you are going to take longer, but we can’t be responsible for your time and we are likely to have packed up. The marshalls track the back runner around the course to ensure that everyone makes it home safely.
I don’t know if I’m old enough
Guidelines suggest that you need to be at least 17 to run 13.1miles. If someone below this age wishes to run, please get in touch via the queries form. We may request that a parent takes full responsibility.
I entered the half marathon, but now want to run the full marathon or I entered the full marathon, but now want to run the half marathon. What should I do?
You don’t need to do anything with regards to entry. We have enough transport from the half finish to ensure that everyone who finishes there can be taken back to the Sports Centre. In short, we ask who’s running the full or the half so we can get a rough estimate of how much transport is needed at the half marathon finish and how medals of each sort to order.
I entered the half marathon but think I might carry on if I feel good at the half finish. What should I do?
Anyone who’s entered can simply carry on when they reach the half marathon finish if they so wish.
Will there be prizes?
Everyone receives a finishing medal. Due to the nature of the event we prefer to encourage friendly rather than competitive competition and thus do not offer cash prizes to those who finish high up. We do however believe that more races should put some effort into providing good cash prizes for the athletes who win.
What happens if the event gets cancelled?
It is highly unlikely that the event will be cancelled. However, if there is a meteor strike, the Earth implodes, global warming so severe that humans start cooking or perhaps several metres of snow then we may consider postponing the event. In such an event we will be unable to offer refunds, but we suspect this will be the least of your worries. If extreme weather (such as flooding) means that the course has to be adapted, we will notify you immediately and send a copy of the updated course.
What if I need to withdraw?
Sadly, we are unable to offer direct refunds for those who can’t race.
What should I wear?
You should wear clothes appropriate for running in – that being lightweight and comfortable including a good pair of trainers. Up&Running, our sponsors, provide an excellent range of apparel and we encourage you to utilise the 15% you got off from your 2020 number.
I go wrong on the course – what do I do?
This shouldn’t happen. However, in the unlikely event that it does, we recommend the first thing you should do is stop running and think back to the last point that you saw a clear indication of the course and attempt to retrace your steps back to this. It is advisable to carry a mobile phone with you with the route downloaded so that you can easily navigate.
In case of emergency call one of these numbers: 07939680749 07719322623 and we will arrange a car to be with you ASAP
Is there food and water en route?
We provide 5 stations in total. The first station is just south of Grantchester 5 miles into the race where only water and squash are supplied. Following this station, there are 4 further stations which provide hydration and food. NB: it is primarily biscuits, sweets, and fruit at each station. There are vegan options at every station.
Is the race UKA certified?
The race is not UKA certified.
Unfortunately we are not able to provide refunds for entries.
