1913 - The first International Six-Days (then 11th Six Days Reliability Trial - First International Tourist Trial), was an international time test for national Teams, each team consisting of three riders, riding nationally manufactured bikes and competing for  the award of the World Trophy, also known as the "Motorcycle Olympics", held in Carlisle, Great Britain from 18th to 23rd August 1913.
The winning team turned out, of course, to be a British crew, composed of W. B. Gibb, W. R. Little and C. R. Collier.
As proof of what the elitist participation in such events, it is no coincidence that the Captain of Team, Charlie Collier, was the son of the owner of the Matchless factory.
The three French riders, who did not expect such a heavy commitment, retired on the morning of the second day, while the American "Teddy" Hastings, fought longer, but did not finish the test.
For the first time, the bikes were entered by engine capacity, there were more classes which were assigned different hourly averages, in order to make the classifications fairer.
Of the 162 motorcycles, including some side-cars, which took off, only 99 finished the event. 51 gold medals were awarded, 21 silver medals and 27 bronze medals, while 63 were counted as retired.
On this occasion, however, the foundation of the regulations remained active and apart from some rules these remained active for several years.
For example, the basic rule to maintain a given average speed for the whole of the competition was established, coupled with tests of ability and speed.
As for the ranking, points would be removed in the case of deviation from the route, the use of spares not carried by the rider and stopping in a non-stop area.
The poor condition of the machinery and the level of cleanliness of the riders were also entered as evaluation criteria.

1914 - Like the Olympics only with an annual cadence, the Six days has continued to take place in various nations apart from the period of the two world wars.
Even the next year’s competition to be held in Grenoble France was quickly abandoned after initially starting, following the outbreak of the First World War.
For the same reason the competition was suspended between 1915 and 1919.

1919 – The wars had the effect of suspending competition everywhere but technological progress did not stop.
In fact it found new and consistent stimuli following the deliberate use of the motorcycle in the various theatres of war.
The industry therefore came out of the conflicts reinforced and the return of peace coincided with the pick-up of the old competitions to which new events were added.
In Italy in 1919 the ‘Freccia del Sud’ (the ‘arrow of the south’) was instigated, a north-south raid starting from Milan and arriving in Caserta.

1920 – Unfortunately the war had left its scars and there were only fifteen riders at the start. But the ISDT was re-born.
The second edition of the Six-Days (ISDT) was held once more in Grenoble in August 1920 and the world Trophy highlighted the Swiss team of J. Morand, A. Robert and E. Gex.
The victory of Team Switzerland, was certainly the merit of the excellent riders who took the title, but it is also an occasion to remember the supreme value of peace. Indeed, the only European nation that had not taken part in the World War, and who therefore had not suffered its the devastation, was certainly advantaged in setting up a strong and well equipped team so that part of the credit for the victory was certainly the result of shrewd Swiss neutrality.
So it was that the great cup re-started its journey outside England, to be assigned to the winning nation with the responsibility of custodian until the next event.
On the base of the cup a silver plate bore the name of the winning nation and the host country.
Initially a regulation was introduced that said that the organisation rights lay with the country which organised the last event, but with time this was abandoned because of the practical difficulties this involved.

1921 – The editions of 1921 and 1922 were held in Switzerland and on both occasions the host nation always came out on top, winning the top steps of the podium.
From 1st to 6th August 1921, the 4th edition of the ISDT was held in Geneva, and the Trophy was taken by the crew composed of J. Morand, A. Rothenbach and E. Gex.

1922 – The following year the Swiss did an encore with the crew, slightly different, consisting of J. Morand, A. And Robert E. Gex. Also in 1922, a few kilometers from Paris at the Vajours circuit, at four in the afternoon of May 27, the first edition of the Bol d'Or kicked off, one of the most famous endurance races in the history of motorcycling.
28 riders took part in the first edition, of which only half of them crossed the finish line. The race was won by a certain Tony Zins, on a Motosacoche 500, which traveled the 1,245 kilometers and 628 meters race at an average of 51.9 km/h.
