The Buenos Aires Half Marathon is one of the most important in Latin America and attracted more than 25,000 runners from all over the world.

Dare to run the fastest half marathon in Latin America.

Mountain race, with numerous passages in high altitude (>2500m), in difficult weather conditions (night, wind, cold, rain or snow), that needs a very good training, adapted equipment and a real capacity of personal autonomy.

It is 6:00pm and we are more or less 2300 people sharing the same dream carefully prepared over many months. Despite the incredible difficulty, we feel serene thanks to the help and comfort offered with by 2000 volunteers who in a spirit of sharing and friendship are ready to partake in the same adventure.

We are about to take off on a dream-world adventure.

We will be rubbing shoulders with Aiguille de Bionnassay and crossing Col du Bonhomme by moonlight. At sunrise, we will cross Col de la Seigne into Italy and the magical Val Veni overlooked by Noire du Peuterey and the glaciers descending Mont Blanc. Later we will reach the Val Ferret, guarded by Dent du Géant and Grandes Jorasses before finally turning into Switzerland to relish the beautifully protected countryside.

We will have to put up with fatigue, to overcome our fears and anxieties. Some participants, having pushed their limits to the extreme, will choose to break off the race keeping intact their hopes to make it from beginning to end at some later date. They will be rewarded for their achievement and their names will be added to the list with everyone else at the end of the race.The others will climb over Bovine and Les Tseppes. Then, with Aiguille Verte in front of them, under the vertical heights of the Drus and with majestic presence of Mont Blanc before them, they will dive down towards the finishing line in the heart of Chamonix.

Stockholm Half marathon has a unique course. Starting and running in the area between the castle, the Riksdaghuset and the Opera is special. And running in the middle of town is really a special feeling.

The half marathon in Stockholm has been called Stockholm Halvmarathon (Stockholm Half Marathon) since 2007 but the race is actually much older. In 1927, the year the first Volvo car was produced and Charles Lindbergh flew non-stop across the Atlantic, was when Stockholmsloppet (Stockholm Race) was launched.

The race was organised by athletic club Fredrikshof IF and the newspaper Stockholms Dagblad whose sports writer, Oscar Söderlund, came up with the idea of the competition.

The first race started and finished in the Olympic Stadium, later editions used the open-air museum of Skansen and the national football stadium in Råsunda.

The race was international and until its demise in 1955 one of the major events in Swedish distance running. From 1933-1936 Thore Enochsson won four times, before the Finn, Erkki Tamila followed up with three consecutive victories.In the 1950s Uno Gustavsson became the third man to win the race three times.
