Cambridge Half Marathon 2027: Course, Entry & Race Guide (14 March)

Few half marathons let you run past centuries-old university colleges, along the River Cam and out into English countryside — all on traffic-free roads and in a single, flat lap. The Cambridge Half Marathon does, and that’s why it now sells out within hours.

The 2027 Cambridge Half Marathon takes place on Sunday 14 March 2027. The 2026 race, its 15th edition, saw more than 14,000 runners finish, and demand keeps growing. Here’s everything you need to know to get a place and race it well.

How to Get a Place

Getting into Cambridge is now the hardest part of the race. The 2026 edition sold out within hours of entries opening, and organisers give priority access to people on the official mailing list. If you want to run in 2027, sign up at cambridgehalfmarathon.com and watch for the entry announcement — don’t wait for general sales.

Entry fees have been around £44 in recent years, with a small discount for runners affiliated to an athletics club. Check the official site for 2027 pricing.

Charity Places

If you miss out, charity places are the best route in. Cambridge has a large charity field, with places offered by local and national charities including Addenbrooke’s Charitable Trust, East Anglia’s Children’s Hospices, Macmillan Cancer Support, Cancer Research UK and the MS Trust. Each charity sets its own fundraising target.

Why Run Cambridge?

A Course Through History

The route follows and crosses the River Cam, runs through the grounds of the university, and passes some of England’s most famous historic buildings before heading out into open countryside at Grantchester and Trumpington. It’s one of the most beautiful half marathons in the UK — and almost entirely free of traffic.

Flat and Fast

Cambridge is one of the flattest cities in England, and the course reflects that. A single lap, flat roads and cool March weather add up to a genuine PB opportunity. The 2026 men’s race was won in 1:04:15, with Cambridge & Coleridge AC sweeping the podium.

A Big Race With a Local Feel

With more than 14,000 runners, Cambridge is one of the largest half marathons in the East of England. Yet it still feels like a local event, with crowds, cheer points and music along the route and a community hub at the finish.

Perfect Timing for an April Marathon

Mid-March is ideal for runners targeting an April marathon such as London. Racing Cambridge five to six weeks before your marathon gives you an accurate fitness check, enough time to recover, and a realistic basis for your marathon goal.

The Cambridge Half Marathon Course

The race starts and finishes on Midsummer Common, close to the city centre and the river.

The Start: Midsummer Common

Four start gates help spread the field and reduce congestion in the first mile. Even so, the opening section is busy — let the crowd settle you into a sensible pace.

The City and the University

The early miles take in the historic city and the university grounds, including a short off-road section. Expect narrow sections, tight turns and plenty of spectators. This is the most memorable part of the race — enjoy it, but stay patient.

Out to Grantchester and Trumpington

The course then heads out into open countryside south of the city. The roads are quieter and more exposed here, and if there’s a wind, this is where you’ll feel it. It’s also the part of the race where you can settle into a strong, steady rhythm.

Back to Midsummer Common

The final miles return toward the city and the river for the finish on Midsummer Common. A water station at mile 12, added in 2026, gives you one last drink before the push to the line.

Racing Cambridge Well

1. Be Patient in the First Mile

With more than 14,000 runners, the first mile is crowded. Don’t weave — it costs energy and distance. Settle in, and you’ll find space soon.

2. Watch the Weather

March in Cambridge is usually cool, but conditions vary. In 2025, warm weather led to the race running short of water; in response, organisers added a fifth water station at mile 12, electrolyte drinks at selected stations and better post-finish hydration. Check the forecast in race week and adjust your plan if it’s warm.

3. Use the Countryside Section

The quieter, flatter roads around Grantchester and Trumpington are the best place to lock into goal pace. If it’s windy, work with other runners.

4. Run the Tangents

Cambridge’s historic streets mean plenty of turns. Take the shortest line through every corner.

5. Save Something for the Finish

The last mile back to Midsummer Common is where you can make up time — if you haven’t spent it early.

How to Prepare

Training Plan

For a 14 March race, a 10-12 week block starts in late December or early January, which means a winter build.

• Long runs: Build to 18-22km, with goal-pace segments in the later runs
• Threshold sessions: One tempo or threshold session each week
• Speed: Shorter intervals early in the block
• Race practice: A 10K in February is an ideal fitness check

Training Through Winter

• Protect your key sessions. Dark, cold mornings make it easy to skip runs; make your long run and threshold session non-negotiable.
• Use the treadmill when needed. On icy days, a treadmill session is better than none.
• Dress in layers. Start warm and shed layers as you go.

Clash Watch

The Bath Half falls on the same day — Sunday 14 March 2027. If you’re choosing between them, Cambridge offers a flat, single-lap course through the colleges and countryside; Bath is a two-lap city race with big crowds and a few more gentle hills.

Race Weekend Logistics

• Getting there: Cambridge is under an hour by train from London King’s Cross or Liverpool Street. Trains on race morning can be busy, so allow extra time.
• Where to stay: Book early — accommodation in Cambridge fills up on race weekend.
• Race morning: Plan to arrive at Midsummer Common well before the start for bag drop and toilets.
• Women’s facilities: Women-only toilets and free sanitary products returned in 2026.

After the Race

Keep moving, drink, eat and get warm quickly — March mornings can be cold once you stop. Take a few easy days before returning to training, especially if you’re building toward an April marathon.

Log It While It’s Fresh

Write down your time, splits, the weather, how crowded the first mile was and how you felt in the countryside section. If Cambridge was a marathon tune-up, record what your result means for your marathon goal while it’s still fresh.

Is Cambridge Right for You?

It’s Great If You:

• Want a flat, fast, traffic-free spring half
• Love historic scenery
• Are building toward an April marathon
• Like big-race atmosphere with a local feel

Consider Other Options If You:

• Can’t commit to entering as soon as entries open
• Prefer smaller, quieter races
• Dislike crowded starts and narrow sections

Final Thoughts: Cambridge Half Marathon 2027

Cambridge combines a flat, fast course with some of the most beautiful scenery in British road running: the colleges, the River Cam and the countryside beyond. It’s well organised, it has learned from past years, and it’s perfectly timed for a spring PB or an April marathon tune-up.

The challenge is getting in. Join the mailing list, be ready the moment entries open, and if you miss out, look at charity places. Then train through winter and get ready for a fast morning in Cambridge on 14 March 2027.
