The world's first underwater half-marathon!

Written by  Jun 17, 2019

October 5th, the world's first and only underwater half-marathon will be held in the new Ryfast tunnel. A 14.3 kilometer long subsea tunnel between Solbakk in Strand and Hundvåg in Stavanger.

5000 competitors will participate in this special underground hill-climb race. Probably the largest underground hill-climb run in history.

The Ryfylket tunnel will provide connection between small communities and the large city municipality of Stavanger, Norway. A large population travel daily by ferry, and will in the future travel through this 50 km long tunnel project, consisting of three main tunnels.

When the tunnel is finished, it will be the longest subsea road tunnel in the world. Part of the tunnel has a incline of 7 %. At the deepest, the tunnel is 292 meters below sea level.
