Saturday 31.7.2021 it is time for the 7th edition of Bomarsund Trailrun. The distances are the same as 2020 i.a an easier 1km for the youngest participants, 4,5 or 12km with start- and finish line by the competition area in Bomarsund and the newest 28km distance starting at Kastleholm castle and the finish in Bomarsund – all routes along historical paths in a mighty landscape.


Welcome to Bomarsund Trailrun 31.7.2021

Imagine August 1854 when the Bomarsund period came to an abrupt end. After Russian forces for over two decades had worked to build Bomarsund fortifications everything was destroyed in a few days at a English- French attack.
Let the race take you to areas including those that Lieutenant Zvendjeff at Notvikstornet and towercommandant Tesche at Brännklintstornet tried to defend with their troops. Run along the same paths that medical staff used to take the injured to hospital, as the messengers took to convey messages to the fortress commandant Bodisco and used at funerals to bring their men to his final resting place.

The same day in the forenoon Bomarsund Openwater will take place in the surroundings. An open water event that offers three different distances – 3000 meters, 1500 meters and 400 meters with both competition- and open classes.
