The 10 Best Half Marathons in the World (2027)

What a "best" half marathon actually means, and why the label matters

The phrase "Best Half Marathons in the World" gets thrown around loosely, but the races that consistently earn the label do so on four measurable axes, and those axes pull against each other more than most runners expect.

Course speed. A half marathon course is 21.0975 km. What separates a fast one from a slow one is net elevation change, the number of 90-degree turns, road camber, and the width of the start funnel. The Lisbon Half Marathon starts on the Vasco da Gama Bridge and runs net downhill; Valencia is flat and at sea level; Copenhagen is a smooth, wide loop through the Danish capital. These three are the reason elite half marathon world records keep landing in the same handful of postcodes. By contrast, a course with eight tight turns per mile can cost a mid-pack runner 45–90 seconds over 13.1 miles purely in deceleration and re-acceleration, even before hills enter the picture.

Certification. World Athletics course certification (and the associated Label Road Race tiers — Label, Elite Label, Platinum Label) is what makes a time count for records and rankings. A certified course has been measured by the calibrated bicycle method with a short-course prevention factor built in, meaning the route is deliberately measured slightly long so it can never come up short. If you want your half marathon PR to mean something outside your own training log, run a certified course. The Great North Run itself is a point-to-point course with a net elevation drop and a start/finish separation that exceeds World Athletics record-eligibility limits — a useful reminder that "world's biggest" and "record-eligible" are different claims.

Atmosphere and scale. The Great North Run's roughly 60,000 finishers make it the largest half marathon on earth. Scale changes the experience in concrete ways: continuous crowds instead of intermittent pockets, wave starts spread over an hour or more, and a finish area that functions like a small festival. The Red Arrows flypast over the Tyne and the seafront run-in at South Shields are the reason runners enter a ballot for it year after year rather than picking a quieter, faster race 40 miles away.

Operational competence. This is the axis nobody markets and everybody notices: bag drop that actually returns your bag, portable toilets in proportion to field size, water stations that don't run dry for the back half of the field, accurate pacers, chip timing that works, and a course that's genuinely closed to traffic. The Berlin Half Marathon, Copenhagen Half, and Philadelphia Half all have long track records here. Weak organization is the single most common reason a scenic, cheap race never makes anyone's best-of list.

The reason this matters practically: you cannot maximize all four. Rock 'n' Roll Las Vegas closes the Strip at night and delivers an experience no other 13.1 can match, but a night start, casino-district turns, and a large mixed-ability field make it a poor PR target. runDisney events are engineered for delight — characters, fireworks, park sections — and explicitly not for the clock, with early morning starts and photo-stop congestion. Choosing well means naming your priority before you look at a single race calendar.

The step-by-step process for picking and booking your 2027 half

Treat race selection as a sequence, not a browse. Runners who reverse the order — falling for a destination first, then trying to build training around it — are the ones who end up undertrained on a hilly course in the wrong month.

Step 1: Name the goal. Exactly one of: personal best, first half marathon finish, destination experience, or charity fundraising. This single choice eliminates most of the field. A PR goal rules out night races, park races, and anything with more than modest elevation. A first-finish goal prioritizes generous cutoffs (commonly 3 to 3.5 hours) and dense on-course support. A destination goal legitimately deprioritizes the clock.

Step 2: Fix the date backward from your training. A well-built half marathon block runs 12–16 weeks for an experienced runner and 16–20 weeks for a first-timer coming from a modest base. Count backward from candidate race dates and check the block against your actual calendar — work travel, holidays, family commitments. A March race in Lisbon means base building through a northern-hemisphere winter; a September Great North Run means long runs through summer heat.

Step 3: Check the entry mechanism, because they are not the same. Ballot races (Great North Run) require registration during a fixed window months ahead, with results announced later — you cannot decide in June to run in September. First-come-first-served races (most European city halves) can sell out in days or weeks. Charity places exist for most large UK races and typically carry a minimum fundraising commitment. Tour-operator packages bundle a guaranteed entry with hotel at a premium over the face entry fee.

Step 4: Verify the course profile yourself. Do not trust the marketing copy. Pull the official course map and elevation profile from the race's own site and look at total ascent, not just net change. A course with 120 m of ascent and 130 m of descent is "net downhill" and still has real climbing in it.

Step 5: Book travel around the logistics, not the race day. Arrive two to three days early for any flight crossing more than two or three time zones. Confirm expo hours and whether packet pickup is available on race morning — many large races prohibit it entirely, which turns a missed expo into a missed race.

Step 6: Register early. Entry fees for most large halves rise in tiers as the field fills; late-tier pricing can run meaningfully above the opening tier for the identical race.

Costs, timelines, and typical ranges across the ten races

The spread in entry pricing across the world's best half marathons is wider than most runners assume, and the entry fee is rarely the largest line in the budget.

Entry fees by region. European city halves cluster low. The Valencia Half Marathon runs roughly €40–€60, which is the single best price-to-course-quality ratio in the sport. The EDP Lisbon Half Marathon sits around €40–€55. The Berlin Half Marathon runs about €60–€75, and the Copenhagen Half Marathon about €50–€70. UK races land in the middle: the Great North Run near £64, the Great Scottish Run in Glasgow around £45–£55, and the Bath Half Marathon around £55–£65. North American marquee events sit highest — the Philadelphia Half Marathon around $120–$150, Rock 'n' Roll Las Vegas around $120–$180, and runDisney half marathons around $185–$215, with premium multi-race challenge packages higher still.

Timelines. Registration typically opens 6–12 months ahead for large European halves. US events frequently open a similar distance out but can sell out in weeks rather than months, particularly runDisney weekends, which have historically sold out very quickly. Ballot windows for the Great North Run open and close on fixed dates well over half a year before race day. Build a calendar reminder for the opening date of any race you actually care about — missing the window is the most common way runners lose a season.

The real budget. For a European destination half, expect the entry fee to be 10–20% of the total. Round-trip airfare, two to three nights of accommodation at race-weekend rates (hotels near start areas routinely price up for the weekend), local transport, and meals dominate. A realistic all-in for a European city half from within Europe is a few hundred euros; from North America, it is a multiple of that. Las Vegas and Disney events invert this somewhat — the entry is high, but you were probably going to book the hotel anyway.

Hidden costs worth budgeting. Race photos, if not included. Checked bags for a flight where you refuse to gate-check your racing shoes. Travel insurance, which matters more than usual because half marathon entries are generally non-refundable and often non-transferable. Charity minimums, which for popular UK ballot races can substantially exceed the face entry fee. Deferral fees, where offered at all.

Time investment. Beyond the 12–20 week training block, budget roughly four to six hours of race-weekend logistics: expo travel and packet pickup, a shakeout run, course reconnaissance if you can get to the start area, and the pre-race morning, which for a large half typically means being in your corral 45–75 minutes before your wave goes off. Point-to-point races add a mandatory bus or metro transfer to the start — for the Great North Run's Newcastle-to-South Shields format, the return journey from the finish is its own planning exercise.

Where the revenue goes. It is worth understanding that a major half marathon is a business: entry revenue funds road closures, policing, medical cover, timing, and the medals and shirts, while sponsorship and charity partnerships fund much of the rest. This is why a €45 race in Valencia and a $200 race in Florida can both be well run — different revenue mixes, different cost bases.

Where runners get race selection wrong

Mistaking "famous" for "fast." The Great North Run is the biggest and among the most beloved halves in the world, and it is not the course to chase a certified PR on. Its point-to-point profile with a net drop and wide start/finish separation sits outside World Athletics record-eligibility parameters, and a field of 60,000 means real congestion in the opening miles regardless of your wave. Run it for the experience it is famous for.

Ignoring the total ascent number. "Net downhill" is a marketing phrase. A course can finish lower than it starts and still contain a punishing climb at mile 9. Always look at the full elevation profile, not the start-to-finish delta.

Underestimating congestion cost. In a 35,000-runner field like the Berlin Half, the first two kilometres are slower than your target pace whether you like it or not. Plan for it. Runners who try to make up 40 seconds in kilometre 3 routinely pay for it after 15K.

Booking travel before confirming entry. Especially fatal with ballot races. Do not book flights to Newcastle before your ballot result lands.

Assuming weather from the month. A March race in Lisbon and a March race in Bath are not the same weather bet. Look at historical race-day conditions from the event's own past reports rather than a generic monthly average, and pack for the tail case — a warm autumn day at the Great Scottish Run or a cold, wet one are both plausible.

Treating an experience race as a PR attempt. runDisney events include character photo stops, park sections with narrow paths, and very early start times. Rock 'n' Roll Las Vegas runs the Strip at night with live music and a mixed-ability field. Both are excellent at what they are. Neither is where you go sub-90.

Skipping the expo deadline. Many large halves have no race-morning packet pickup. If your flight lands the evening before and the expo closed at 18:00, you have paid for a race you cannot start.

Over-racing the build. Slotting three halves into a 16-week block leaves no room for the training that makes any of them fast. Pick one goal race per block.

Decision framework: matching the race to the runner

Work down this framework in order and the ten races sort themselves quickly.

If the goal is a certified personal best, the shortlist is Valencia, Lisbon, Copenhagen, and Berlin. Valencia and Copenhagen are flat and fast with excellent organization; Lisbon's bridge start gives it a net-downhill assist; Berlin adds cool April conditions and a major-capital field deep enough that you will always have someone to run with at your pace. Between them, choose on date and travel cost, because the course quality differences are marginal.

If it is your first half marathon, prioritize flat, well-supported, generous-cutoff races. The Berlin Half and the Great Scottish Run both offer big-city support with forgiving profiles. A runDisney half is arguably the most beginner-friendly option in existence — the whole event is engineered around finishing happy rather than finishing fast, though the early start and cost are real trade-offs.

If you want the biggest possible atmosphere, the Great North Run is the answer and it is not close: 60,000 runners, near-continuous crowds from Newcastle to the coast, and a seafront finish.

If you want a genuinely unique experience, Rock 'n' Roll Las Vegas is the only major half that closes the Las Vegas Strip at night, and runDisney is the only one that runs through theme parks. Both trade the clock for spectacle, deliberately.

If budget is the binding constraint, European city halves at €40–€60 — Valencia, Lisbon — plus UK races in the £45–£65 band deliver world-class racing at a fraction of US marquee pricing.

If you are fundraising, UK races with established charity-place programmes (Great North Run, Bath Half, Great Scottish Run) have the deepest charity infrastructure, with dedicated places, fundraising support, and cheering stations.

If travel simplicity matters, favour big-city halves with short airport transfers and dense hotel supply: Berlin, Lisbon, Copenhagen, Valencia. Point-to-point races add a transfer leg on both ends of race day.

Related questions

Which half marathon is the fastest in the world?

Valencia, Lisbon, and Copenhagen are the courses most associated with elite half marathon records — all flat or net-downhill, at or near sea level, on wide, well-surfaced roads with few sharp turns. Valencia in particular has hosted multiple world records at the distance.

How far in advance should I register for a 2027 half marathon?

Register 6–12 months ahead for large European halves and as early as possible for US marquee events, which can sell out in weeks. Ballot races like the Great North Run have fixed entry windows well over half a year before race day — miss the window, miss the year.

Do I need a qualifying time to enter these races?

Most half marathons on this list are open to all runners with no qualifying standard. The constraint is availability, not speed: popular events sell out or run ballots. Elite and sub-elite start corrals typically do require a submitted recent time.

Is the Great North Run eligible for world records?

No. Its point-to-point Newcastle-to-South Shields layout has a net elevation drop and a start-to-finish separation that fall outside World Athletics record-eligibility parameters. Times are officially timed and certified for personal use, but the course cannot ratify a world record.

What should I budget in total for a destination half marathon?

Entry is typically 10–20% of the total. Expect the dominant costs to be airfare, two to three nights of race-weekend accommodation, local transport, and meals. A €45 entry in Valencia can sit inside a trip costing many times that.

FAQ

Is the Great North Run really the best half marathon in the world?

It is the best overall on scale, history, and crowd support — roughly 60,000 runners, a Tyne Bridge start, a Red Arrows flypast, and a coastal finish at South Shields. "Best" is goal-dependent, though: for a personal best, Valencia or Copenhagen beat it on every measure that matters to the clock.

How much do these half marathons cost to enter?

European city halves run roughly €40–€60 (Valencia, Lisbon) up to €60–£75 for Berlin and Copenhagen. UK races sit around £45–£65, with the Great North Run near £64. North American marquee events are highest: Philadelphia around $120–$150, Rock 'n' Roll Las Vegas $120–$180, and runDisney halves $185–$215.

Can I set a personal best at any of these races?

Realistically at four of them: Valencia, Lisbon, Copenhagen, and Berlin. All are flat or net downhill, certified, and organized well enough that you are not fighting the logistics. Weather, field congestion in the opening kilometres, and your own training block still dominate the outcome.

Which of these races are best for a first half marathon?

Berlin Half and the Great Scottish Run combine flat profiles with big-city crowd support and generous cutoffs, typically in the 3 to 3.5 hour range. A runDisney half is the lowest-pressure option available — designed around finishing, not timing — at the cost of a high entry fee and a very early start.

How do ballot, open, and charity entries differ?

Ballot races allocate places by random draw during a fixed registration window months ahead. Open-entry races sell first-come-first-served, usually in rising price tiers. Charity places guarantee entry in exchange for a fundraising commitment, which for popular UK races can exceed the face entry fee considerably.

Are night races and theme-park races worth it?

Yes, if you understand the trade. Rock 'n' Roll Las Vegas is the only major half that closes the Las Vegas Strip at night, and runDisney is the only one running through theme parks. Both deliver experiences no flat European course can. Neither is where you chase a time.
