Brazil has one of the most underrated racing calendars in the world, and one of the most misunderstood.<\/p>\n
Most international runners assume it’s too hot to race there. That’s true in January and largely true in December \u2014 but Brazil’s winter runs from roughly April to July, and in the south that means genuinely cool mornings, low humidity and conditions as good as anywhere in Europe. The country’s biggest races cluster in exactly that window for exactly that reason.<\/p>\n
It’s also a country with enormous regional variety. Running a half marathon in Porto Alegre in July and one in Rio in August are close to different sports.<\/p>\n
Here are ten of the best half marathons in Brazil for 2027, listed in calendar order \u2014 which matters more here than almost anywhere, because the season dictates the experience.<\/p>\n

Free to start.\n <\/p>\n Plan Your Season Free \u2192<\/a>\n <\/div>\n A note on dates:<\/strong> Five of the ten 2027 dates below are confirmed. The rest reflect each event’s established slot \u2014 Brazilian races typically publish four to eight months ahead. Check the official site before booking anything.<\/p>\n The Brazilian racing year opens here.<\/strong> The 20th edition of the S\u00e3o Paulo International Half Marathon falls on Sunday 24 January 2027 \u2014 the day before the city’s 473rd birthday, which is a municipal holiday and turns race weekend into a citywide occasion.<\/p>\n Organised by Yescom, the race is based in the Zona Leste at the Shopping Metr\u00f4 Itaquera, near the Corinthians-Itaquera metro station. The half starts at 6:45am, with a 10K and 5K following shortly after \u2014 a start time chosen specifically to get runners home before the January heat properly arrives.<\/p>\n Around 9,000 runners take part, and a nice touch: your race number doubles as a free TER train ticket on race day.<\/p>\n Best for:<\/strong> Starting the year with something on the board, and experiencing S\u00e3o Paulo at its most celebratory.<\/p>\n Watch out for:<\/strong> This is Brazilian summer. Expect 19-22\u00b0C at the start rising into the mid-20s, with humidity in the 70-85% range. Adjust your goal accordingly \u2014 visiting runners from cooler climates should plan on 5-15 minutes slower than a temperate-climate half.<\/p>\n Island running on Brazil’s best-looking coastline.<\/strong> Florian\u00f3polis sits on an island in the south, with over forty beaches, lagoons and a bridge connecting it to the mainland. The race makes proper use of the setting.<\/p>\n March is the tail end of summer, so it’s still warm \u2014 but Santa Catarina is considerably milder than the southeast, and the coastal breeze helps. The city has one of the strongest running cultures in Brazil.<\/p>\n Best for:<\/strong> Scenery, and a race weekend on one of the country’s best stretches of coast.<\/p>\n Watch out for:<\/strong> Coastal terrain means it rolls, and late summer humidity is still a factor.<\/p>\n The half alongside South America’s biggest marathon weekend.<\/strong> Running since 1995, the S\u00e3o Paulo International Marathon starts and finishes in Ibirapuera Park<\/strong> \u2014 the city’s great green space \u2014 and offers a half marathon, 10K and 5K alongside the full distance.<\/p>\n The marathon draws over 30,000 runners across the weekend, making it the largest event of its kind on the continent. April timing puts it right at the start of the good-weather window, which is a large part of why it’s grown the way it has.<\/p>\n Best for:<\/strong> Big-event atmosphere and the best conditions S\u00e3o Paulo offers.<\/p>\n Watch out for:<\/strong> S\u00e3o Paulo is not flat. The city sits on a plateau of rolling terrain and the course reflects it.<\/p>\n The most spectacular urban course in the Americas.<\/strong> The Rio de Janeiro Marathon has run since 1979, and the half marathon takes place on the Saturday of race weekend, ahead of the marathon on Sunday.<\/p>\n The course runs along the coast past Copacabana and Ipanema<\/strong>, with Sugarloaf and the surrounding mountains as a backdrop. It is, by a reasonable distance, one of the best-looking road races anywhere.<\/p>\n Late May puts it right at the start of Rio’s winter, which means the most comfortable running conditions of the year \u2014 warm rather than hot, with far less humidity than the summer months.<\/p>\n There’s also the Desafio Cidade Maravilhosa<\/strong> (“Wonderful City Challenge”) for those inclined: run the half on Saturday and the marathon on Sunday. Around 1,400 runners completed it in 2022.<\/p>\n Best for:<\/strong> The single most beautiful race on this list, at the start of Brazil’s best racing window.<\/p>\n Watch out for:<\/strong> It’s a destination race and priced accordingly. Book accommodation early \u2014 Rio race weekend fills up.<\/p>\n Germany in southern Brazil, and one of the country’s coolest race days.<\/strong> Blumenau was founded by German immigrants in 1850 and still looks it \u2014 half-timbered architecture, a serious brewing culture, and the largest Oktoberfest outside Munich.<\/p>\n July is the coldest month of the Brazilian year, and in Santa Catarina that means genuinely crisp running conditions \u2014 occasionally single digits at the start, which is remarkable for Brazil.<\/p>\n Best for:<\/strong> Cool-weather racing, and a version of Brazil that surprises most visitors.<\/p>\n Watch out for:<\/strong> The Itaja\u00ed valley setting means some rolling terrain, and it genuinely can be cold at the start. Bring a throwaway layer.<\/p>\n The fastest conditions in Brazil.<\/strong> If you want a Brazilian personal best, this is the race.<\/p>\n Porto Alegre sits in the far south, and its July race combines the country’s coolest weather with a flat course along the Gua\u00edba waterfront. Where most Brazilian races ask you to manage heat, this one simply doesn’t \u2014 it’s a legitimate PB opportunity rather than a survival exercise.<\/p>\n The ga\u00facho running community is also among the most committed in the country, which shows in the turnout.<\/p>\n Best for:<\/strong> A genuine time attempt, and the flattest, coolest option available.<\/p>\n Watch out for:<\/strong> Winter in Rio Grande do Sul can also be wet and windy. Cool is not the same as easy.<\/p>\n Running through a UNESCO-listed city that was designed from scratch.<\/strong> Bras\u00edlia is unlike anywhere else in Brazil: purpose-built in the 1950s, laid out to a modernist plan, and full of Oscar Niemeyer architecture with enormous open spaces between it all.<\/p>\n For runners that translates into wide roads, long uninterrupted stretches and very little congestion. It also sits at around 1,100m, which is high enough to be mildly noticeable if you’re coming from sea level \u2014 and high enough that the mornings are genuinely cool. July is mid-winter and the driest month of the Bras\u00edlia year, which makes this one of the better-conditioned races on the list.<\/p>\n Best for:<\/strong> Architecture, wide-open running, and cooler temperatures than most of the country.<\/p>\n Watch out for:<\/strong> The altitude, mild as it is, plus the dry season sun and very low humidity. Bras\u00edlia in July is bright, arid and dehydrating \u2014 drink more than the temperature suggests. It also shares its weekend with the peak of the July racing cluster.<\/p>\n Rio’s standalone half, and a different race from the June marathon weekend.<\/strong> Held in August and organised by Yescom, this is a dedicated half marathon with a 5K alongside it rather than an add-on to a marathon programme.<\/p>\n That focus is the appeal \u2014 the whole event is built around the distance, and August in Rio is still comfortably within the good-conditions window.<\/p>\n Best for:<\/strong> Rio’s coastline without the marathon weekend around it.<\/p>\n Watch out for:<\/strong> Don’t confuse it with the June race when booking. They’re separate events with separate registrations.<\/p>\n Brazil’s most liveable city, and a well-organised race to match.<\/strong> Curitiba is internationally known for urban planning \u2014 extensive parks, a pioneering transport system, and a general orderliness unusual for a Brazilian city of two million.<\/p>\n That translates well to road racing. The course runs through the parks and boulevards that made the city’s reputation, and September sits at the edge of the good-weather window with mild spring conditions.<\/p>\n Best for:<\/strong> Excellent organisation, green space, and a mild-climate southern option.<\/p>\n Watch out for:<\/strong> Curitiba sits at around 930m and has rolling terrain. It’s comfortable rather than fast.<\/p>\n The hills, and the food.<\/strong> Belo Horizonte is ringed by mountains and built across them, so any race here involves genuine climbing \u2014 the name translates as “beautiful horizon” for a reason.<\/p>\n Minas Gerais is also widely considered Brazil’s best culinary region, which makes the post-race meal a serious proposition. The city’s running community is large and welcoming, and October offers reasonable conditions before the summer heat returns.<\/p>\n Best for:<\/strong> A challenging course, and the best eating of any race weekend on this list.<\/p>\n Watch out for:<\/strong> The elevation change is real. This is not a PB course, and October is warming up.<\/p>\n This is the part that matters most, and the part most international runners get wrong.<\/p>\n Hot and humid across most of the country. Races happen \u2014 S\u00e3o Paulo’s January half among them \u2014 but they’re early-morning affairs and nobody is chasing a PB. If you’re racing in this window, start times are before 7am for good reason.<\/p>\n This is when Brazilian road racing actually happens. Conditions become genuinely good, and the further south you go the better they get. S\u00e3o Paulo on 4 April, Rio on 29 May, then a dense July cluster with Blumenau, Porto Alegre and Bras\u00edlia \u2014 these are the months to target.<\/p>\n For northern-hemisphere runners this is a useful thing to know: Brazil’s best racing window falls squarely in your summer, when your own calendar is quiet.<\/p>\n Still good early on \u2014 Rio in August, Curitiba in September \u2014 before conditions warm through October and November.<\/p>\n One race in the April-July window as your A race, with a January or October event as a supporting effort. Don’t build a season around the summer months; use them for base building the way Brazilian runners do.<\/p>\n Even in the good months, most of Brazil is warmer than what European or North American runners train in. A few practical points:<\/p>\n \n \ud83c\udfaf Picked your races?<\/strong>\n <\/p>\n \n Log them in RunningLog as planned races, set your A\/B\/C priorities, and track every finish alongside your PBs. Free to start, no credit card needed.\n <\/p>\n Start Your Free Race Log \u2192<\/a>\n <\/div>\n If you want the most beautiful race, run the Rio half on 29 May along Copacabana and Ipanema. If you want a genuine time, go to Porto Alegre in July. If you want the biggest occasion, run S\u00e3o Paulo. And if you want the version of Brazil nobody expects, run Blumenau in July and find yourself starting a half marathon in single-digit temperatures in a half-timbered German town.<\/p>\n The key is timing. Brazil’s racing season is April to July, it’s the inverse of the northern hemisphere’s, and it’s considerably better than its reputation suggests.<\/p>\n Ready to plan 2027?
