Manchester Marathon for a PB, Brighton to get in: the UK races after the London ballot
Five British startlines, and not one of them gives you the same day. A point-to-point through Trafford that two thirds of a field ran a personal best on, a marathon that finishes in a different town from the one it starts in, six miles of clifftop above Brighton Marina, and a Gold-label half that waits until mile 12 to put a hill in front of you.
Read the United Kingdom as one big marathon and four alternates and you will get every one of them wrong. Manchester is a one-way road from Old Trafford to Oxford Road that the organisers call the flattest of the British majors, with roughly two thirds of the 2025 field setting a personal best on it.
Edinburgh leaves Potterrow and does not come back — it ends 26.2 miles away on the coast at Musselburgh, into a headwind that runners keep writing about. Brighton spends miles 7 to 13 on a clifftop above the marina before dropping onto the seafront beside a 143-year-old electric railway.
Cardiff is 13.1 miles of closed city road with a World Athletics Gold label on it, the highest grade in this group after London, and a steep climb on Fairoak Road at mile 12 that settles more finishing times than the flat ten before it. Five races, five different things on offer, and five completely different ways of saying yes.
1Manchester: point to point from Old Trafford, flat and fast
Trafford Arch, beside Old Trafford, a little before nine on a Sunday morning in April. The elite wave goes at 08:55 and the rest of the field leaves in staged waves behind it, with official advice to arrive at least 45 minutes early. Then the road runs one way and only one way: Stretford, Sale, Altrincham, Chorlton, and into the city to a finish on Oxford Road outside the University of Manchester.
42.2 km, point to point, nothing repeated and no loop to run twice. What the course gives, the transport takes back a little. Road closures cover the route across Greater Manchester on race morning, driving is discouraged outright and there is no official shuttle.
Metrolink is the route in — Old Trafford or Trafford Bar, about a ten-minute walk, for anyone arriving before 09:30; after that runners are redirected to Wharfside or Exchange Quay. From the finish it is roughly fifteen minutes on foot to Deansgate-Castlefield. On the course itself there are eight water stations with toilets, a gel station, and a medal and shirt at the end.
Entry for 2027 opened on 19 April 2026 and closed on 28 April 2026. Inside those ten days more than 40,000 places went and the public allocation sold out entirely, leaving the charity route as the way in. The 2027 entry fee, start time and course time limit are not published yet.
The organisers describe the profile as long gentle straights on a flat course and call it the flattest of the UK’s major marathons. The claim arrives with a number attached rather than an adjective: roughly two thirds of the 2025 field set a personal best. This is the British marathon people choose when the day is about the clock, and the 2027 edition was declared the largest yet at 52,000 entries.

2Edinburgh: start in the city, finish in Musselburgh
Potterrow, in the middle of Edinburgh, at 10:00 on 29 May 2027. The marathon leaves the city and does not return. It runs point to point out to the East Lothian coast and ends at Musselburgh, which makes it the only race in this group where the finish and the start are in different towns and the journey home is a separate decision.
The course is fast and flat, and both of its problems come straight out of that. The opening city sections are narrow and crowded, which drags people through the first miles faster than they planned. Then the coast.
Runners’ own accounts of recent editions keep returning to the out-and-back stretch past Gosford and Prestonpans, where the headwind arrives late in the race, and to one edition that produced hail, sun and rain inside a single morning. Race-day temperatures typically run 10 to 16C. What those same accounts also describe is a crowd.
One runner writes of hitting 39:17 and questioning what they were doing out there, then finding supporters still cheering through the hail; another calls it the best day they have had in a race. Several first-timers describe hitting the wall between miles 20 and 24 and being carried through it. A half marathon, a 10K, a 5K, a children’s event from 1K to 5K and a four-person relay run under the same festival banner.
Getting there is unusually simple. Trams run every 7 minutes from the airport into the centre, the nearest stop to the start is Princes Street at roughly a fifteen-minute walk, and Waverley is walkable too. Foreign contactless cards tap straight onto Lothian Buses and the trams with a daily cap — a bus single is about £2 and a tram single about £2.10 — so no local travel card is worth buying.
From Musselburgh, buses run back into the city with an extra race-day shuttle between Seton Sands and Prestonpans covering the closure gaps. The expo is at Dynamic Earth in Holyrood Park, standard entry is £84.50, and the time limit is 6 hours 30.

3Brighton — clifftop hills at miles 7 to 13, then the seafront
Brighton is the one that looks like a flat seafront run in photographs and is not. It starts at Preston Park, runs through town past the Royal Pavilion and the Theatre Royal, and then climbs. Miles 7 to 13 are clifftop: out to the turn at Ovingdean, with the sea on one side and Brighton Marina below.
Rises come at miles 1, 7, 9 and 11, and about 200 m of block paving at mile 4.5 breaks up the surface underfoot. From mile 15, at the Aquarium junction, the race drops onto the coast and follows the 143-year-old Volk’s Electric Railway — the Palace Pier, the i360 tower, the Grand Hotel and the Peace Statue in sequence. The coloured beach huts and the Hove Plinth arrive at mile 25, and the finish is Hove Lawns.
Water sits at miles 2, 4, 6, 8, 10, 12.5, 14, 16, 18, 20, 22 and 24. One logistical trap sits in front of all of it. Preston Park and London Road stations are both closed on race morning until 11:00, which makes Brighton station the nearest open one, and the roads around the start close from 06:30.
Park & Ride runs from Mill Road, Falmer, Moulsecoomb and Brighton Racecourse, 25 to 30 minutes each way, with buses to the start between 07:45 and 09:30; it has to be booked and it often sells out. The start is 09:45, the limit is 7 hours — the most generous of the five — and there is no ballot at all: entry is first come, first served, early bird £74.99 and standard £79.99, with entries for the following year opening on race day itself. It is also, quietly, a London race.
Brighton Marathon Weekend was founded in 2010 and is run by London Marathon Events, and three events share the weekend of 3 and 4 April 2027: the Brighton Miles, the Brighton & Hove 10K and the marathon. Runners’ accounts of it are unusually consistent about who it suits — supportive crowds, a welcoming atmosphere, and slower and first-time marathoners describing a day they got through without hitting the wall.

4Cardiff Half, a castle start and a steep climb at mile 12
The highest-graded road race here after London is a half marathon. The start line sits just outside Cardiff Castle on Castle Street, the finish is a grandstand at the Civic Centre in the middle of the city, and all 13.1 miles in between run on closed, marshalled city roads past the Principality Stadium and Cardiff Bay. The scale earns a paragraph.
Barnardo’s founded the race in 2003 with 1,500 runners. It now registers more than 27,500, with elite men’s, women’s and wheelchair races run alongside, the Welsh Half Marathon Championships every year, and both the 2016 World Half Marathon Championships and the 2018 Commonwealth Half Marathon Championships held on these roads. Course records stand at 59:22 for the men, set by Ismau Dilu of Ethiopia, and 1:05:52 for the women, set by Edith Chelimo of Kenya in 2017.
It carries a World Athletics elite road race Gold label and is one of the SuperHalfs with Lisbon, Prague, Berlin, Copenhagen and Valencia, so finishing stamps a Super Passport. Pacers run in every start wave. The confirmed edition on record is Sunday 4 October 2026.
Wheelchair athletes start at 09:50, elites and the white, green and red pens at 10:00, and blue, purple and yellow at 10:10, with a 4-hour limit after which the roads reopen. Entry ran as a ballot in two versions — a UK ballot at £58 and an international one at £70 that allowed teams of up to three on a single application, where one named entrant goes into the draw and a win places the whole team. Booking fees sit on top, the registration deadline was 1 September, UK-based entrants get race packs by post and entrants based outside the UK collect at the Event Village on City Hall Lawns from 12:00 on the Friday.
The surface is mostly flat, with two exceptions, and the second one is badly timed on purpose or otherwise: a ramp on the approach to Cardiff Bay around mile 6, and a steep climb on Fairoak Road at mile 12. A hill at mile 12 of a half marathon is a hill placed where nobody has anything left to spend on it.

5London: the course, and a one-week ballot at £79.99
London is in this list for what it puts on the road rather than for its size. Greenwich to The Mall, with three start areas that only merge at Woolwich just short of mile 3, the Cutty Sark between 6 and 7 miles, Tower Bridge at exactly halfway, and then five miles of Canary Wharf where tall buildings and the Westferry underpass push a GPS watch off distance. The last stretch through Tower Hill and Victoria Embankment is laid out kindly for tired legs, and the final turn comes in front of Buckingham Palace.
It is the only Platinum label in this group, and the support is built rather than incidental: cheer zones, live bands and DJs along the route, a toilet at every mile from 1 to 24, and water from 3 miles at 3 mile intervals to 12 and every 2 miles thereafter. The 2027 race runs across two mornings, 24 and 25 April, and the marathon is held on both. Saturday closes The Mall at 17:30 after 7 hours 45 minutes; Sunday keeps a secondary finish at Green Park open until 23:59:59.
The public ballot for it opened on 24 April 2026 and closed on 1 May 2026 — one week, £79.99, 1,338,544 applications — and then nothing until next spring.

Editor's pick
Manchester for a time, Brighton to actually get in. That is the honest split. Manchester is the flattest of the five and puts a figure behind the claim — roughly two thirds of the 2025 field with a personal best — but the 2027 door stood open for ten days and is charity-only now, which makes it a 2028 decision taken in April 2027.
Brighton is its opposite: no ballot at all, entries for next year opening on race day itself, £74.99 early bird, and enough climbing between miles 7 and 13 that nobody should turn up expecting a flat seafront outing. Edinburgh is the one to send a first marathon to, with a caveat. 6 hours 30 leaves room, £84.50 is the cheapest full-marathon entry in the group, and the transport works without any planning at all.
The caveat is the last stretch into Musselburgh, where the wind arrives at the worst possible mile and the runners who have been there all say so. Cardiff is not a consolation prize for people who missed a marathon. A Gold label, more than 27,500 runners, closed city roads for all 13.1 miles and a 4-hour limit make it a hard, fast half on its own terms — and the mile-12 climb on Fairoak Road decides more finishing times than the flat ten that come before it.
London is the one you plan a year around rather than a season: the route is the best of the five and the ballot week is the narrowest.
Five races, four completely different ways in. London and Cardiff both decide by ballot, and Cardiff runs two of them, one of which lets three people enter on a single form.
Manchester decided by typing speed inside a window that lasted ten days. Brighton decides by almost nothing — open the site, or turn up on race day and enter for the year after.
Edinburgh sits between them, with charity entry and a fundraising minimum as the common route. What is undecided stays marked as undecided.
Manchester has published no 2027 entry fee, no start time and no course limit, and its travel guidance still carries 2026 labels. Edinburgh and Brighton both show registration open with no recorded closing date.
Cardiff’s confirmed date on record is 4 October 2026, with a 1 September registration deadline already behind it and no 2027 edition posted yet. None of it is filled in by guesswork.
