It is claimed this is most tickets sold this far in advance of European Athletics’ flagship event, which next year will be part of the first multi-sport European Championships alongside six other sports in Scottish city Glasgow.

The upper tier of Berlin's Olympiastadion is due to be opened once tickets for the Championships, scheduled to take place from August 7 to 12, sell out on the lower tier.

The biggest demand for tickets at present, according to organisers, is for the evening sessions on August 10, 11 and 12.

"It is not even 10 months until the start of the European Championships," Frank Kowalski, managing director of Berlin 2018, said.

"Our goal is to host the best track and field championships ever in August 2018. 

"For this, we are working as a team with a lot of passion and commitment at Berlin 2018. 

"We are looking forward to exciting and busy months ahead, which we will tackle with great momentum behind us."

Kowalski delivered a presentation on Berlin 2018 during the official opening of the European Athletics Convention and Congress, due to conclude here in Lithuania’s capital today.

He said the overall target for ticket sales is 275,000 and expressed his confidence that the 100,000-barrier will be broken within the next few weeks.

Kowalski revealed that Berlin 2018 is cooperating with external events in an effort to increase awareness of the Championships.

The Local Organising Committee is also creating its own promotional events as part of its strategy.

Interaction with athletes, through social media, was another promotional method identified by Kowalski.

A special feature of the Berlin 2018 qualifying day on August 6 is that admission to the Olympiastadion will be free.

Spectators will be able to experience the qualification in the men’s hammer throw and long jump, as well as the first qualifying rounds in the men’s and women’s 100 metres and men’s 400m hurdles.

There will be no tickets on sale for the qualifying day with details on access to the venue and the areas which will be accessible due to be announced at a later date.

Berlin 2018 claimed it is also "well on the way" in terms of construction work at the Olympiastadion, with modernisation of the venue said to be "almost complete".

The famous blue track, on which Jamaican sprint king Usain Bolt set his world records over 100m and 200m in 2009, has been re-laid in an attempt to ensure optimal conditions for athletes.

The modernisation of the Hanns-Braun Stadium and Mommsen Stadium, which will serve as training and warm-up areas, has not yet been completed.

Berlin 2018 insisted, however, that this is on track to be finished on time.
