At several international ProBase Wingsuit Races competitions at Switzerland, Oliver participated and performed many good final results.

The jumps were made from the ‚Mürrenfluh’ (1600 meters above sea level), the landing spot was located at the village of Stechelberg (922 meters ASL).

The goal was to cover the flying distance between the departure and landing point in the shortest time possible. This can only be done by wearing an aerodynamically perfect wingsuit which allows for an optimized ratio between sink and glide rate. The event was very successful and has the potential to become a recognized Worldcup race.
