I first raced the Cambridge Half Marathon in March 2020 just before the Pandemic broke out and the world came to abrupt halt and had the pleasure of returning in October 2021 when the world had to started to get some sort of normality back.
I returned for the third time in 2025 as part of my 12 half marathons in a year challenge.
It is a really well attended mass race with 15,000 runners on a fast flat course that is perfect for chasing a personal best or just enjoying the beautiful scenery of Cambridge.
ROUTE
The route is a fast flat course with closed roads with only a few very very small inclines.
It is well supported throughout the course especially in the city centre. You get a huge buzz from the crowd on your way back when it is really needed approaching mile 12.
The vast majority of the course is on tarmac closed roads but you do run on some gravel and cobbles whilst running through the grounds of Kings college. For those of you worried about wearing your carbon plated trainers this is a really small section of the course and you are absolutely fine.
Road closures are well advertised in advance and I never felt in danger of any cars at any point when it was half the road closed as they are really wide roads and plenty of room for all runners.
You can view my Strava activity HERE to see elevations and course detail.
WATER STATIONS
There was 4 water stations at 3.5 miles, 6.5 miles, 9.5 miles and 11 miles with small paper cups of water and High5 Aqua gels available at some stations.
PACERS
Whilst pacers were provided it was only for times of 1hr 30mins, 1hr 45mins, 2hrs, 2hrs 15mins, 2hr 30 mins and 2hr 45 mins which leaves a large chunk in between.
For such a large race it would be great if there were pacers at 5 minute intervals but there are plenty of people in your wave that should be running similar times to you.
PARKING
There is some parking in the city centre but you have to be quick as these spaces sell out really fast.
Your best bet is to use the park and ride schemes as there are 5 sites available and you can pay for a ticket when you enter. Just remember to pay for a ticket for each person with you and not per car.
It was super easy parking the car at the park and ride, jumping on the bus and it took you literally 2 minutes walk away from the start/finish area.
It was roughly a 20-30 minute journey from the park and ride but you need to be early as the last bus is at 8:30AM.
TOILETS
There were a huge amount of portable toilets and urinals in the athlete village area and whilst the ques were quite small the vast majority of the time they can get long just before the waves start.
There are also toilets in the holding pen of your wave just before your taking to the start line, which I thought was a great idea for any last minute toilet stops.
MEDAL
Great medal for 2021 but I have a funny feeling it was the same in 2020 but with a different ribbon. I can't find my 2020 medal so I can't be sure. A good solid well made medal though.
PHOTOS
Your entry fee includes professional photos taken at different sections of the course. They are available pretty much straight away thanks to clever software that recognises your race number.
PRICE
The price to enter was £62 which is one of the more expensive half marathons in the UK but it reflects in road closures, mass toilets, bag storage, photos, goody bag that is included in the price. Have completed the race a few times I think it is great value for money.
You can pay for extras like Park & Ride tickets when you enter which was £7 per ticket.
VIP
In 2025, I paid £109 for VIP entry as it includes access to the heated tent, sports massage, refreshments, private toilets and the big plus being the private fast line to the start line.
I thought I would try out the VIP entry to see if it is worth the extra £50+ on top of your £62 race entry.
For me personally, it was worth it for not having to queue for toilets alone! Nothing stresses me out more before a race than having to queue for a toilet and worry of will I need to go again.
The private fast line to the start line was the best part as you could stay in the warm heated tent until your ready to go and be on the start line without queuing within minutes.
Afterwards there was plenty of hot and cold food/drinks and massage available with little to no queues.
WHO ORGANISES IT?
Cambridge Half Marathon is organised by One Step Beyond Promotion also known as OSB Events. They organise the Holkham half marathon/10k and are also known for triathlon events like the Outlaw.
HOW TO ENTER
You can only enter Cambridge Half Marathon via there website but be quick as it sells out every year.
WOULD I DO IT AGAIN?
Definitely, this is a really well organised half marathon on a great course with fantastic support all around the route.
It is a little bit more expensive than most races but I think it is still great value all things considered especially with the major road closures and fantastic goody bag.
THINGS TO BEAR IN MIND...
- Parking is really limited in the city centre and park and ride parking is your best option.
- Friends stayed over at hotel in the city centre and struggled to get a taxi on the day so choose a hotel that is within walking distance.
- The start/finish area does have some catering trucks and this a good location for meeting friends and family.
