The SIMM 2020 takes place as planned on 15-16. August in St. Antönien

The current easing in the event and sports area allows us to announce joyfully: the SIMM 2020 will take place as planned on 15-16. August in St. Antönien (GR). Certain organizational measures are under discussion and preparation and will be communicated to those registered at short notice. The basic concept of the SIMM is retained.

The number of participants including organization must currently be limited to 300 people. We therefore consider registrations in the order of receipt. If more people are later admitted to an event, we will of course accept further registrations.

Current status of SIMM 2020

The current instructions from the Federal Council do not allow any conclusions to be drawn as to whether SIMM 2020 can take place or not. We are still pulling a normal implementation of the SIMM in beautiful Pany-St. Antönien GR into consideration. Whether it can go through the stage like every year or whether we have to choose a different shape remains to be seen. If this is not already on the agenda, please note the date 15th-16th August 2020. There is no alternative date. The decision regarding implementation will be published later.

Help wanted

From 10 to Fri 14 August 2020, i.e. before the SIMM weekend, up to 10 people are busy with various preparations in the running area. Above all, the items have to be set. From Friday evening 14 August 2020 to Sunday evening, around 25 people will take care of the smooth implementation. At the moment there are not enough helper registrations. Who wants to take part in our team as a helper? Regardless of age and fitness, we have the right job for everyone interested.

Cooperation with OTrailrun

The Otrailrun will be held in Ticino for the second time on March 29, 2020. The concept is identical to the SIMM: team of two, orienteering on a national map 1:25 000 and own catering. The Otrailrun the only difference is only one day. It is also always carried out in southern Ticino. The Otrailrun is carried out as project work by elite athletes of the Scuola professionale per sportivi d'élite.
The run is ideal as a training run and material test to prepare for the SIMM. Our former runner Rémy Steinegger and our current security officer Thomas Wiesner (see picture) have already successfully participated last year. They were thrilled with this new run in fascinating terrain.
The two organizations work together and promote each other. The winning teams of the two races win a free start of the other competition.
