We hosted the European Champs back in 2014 and thus there was a lot of funding for young athletes and clubs. But most of it's benefits started to show after the Zurich champs and we have been seeing some success in the last couple of years.
There are actually no athletes that switch narionality just to start for Switzerland. Even the athletes with roots in foreign countries have been living here for a long time and went through our club system. Most of them grew up here. Abraham, todays Marathon silver medalist, is a bit of an exception but even he has been living in Switzerland for 10 plus years and got help from a local track club when he emerged from Eritrea back in the day.
