Doubles Luge described by Team USA luge partners and Sochi Olympians, Jayson Terdiman and Matthew Mortensen:
Luge is an incredible sport but few are familiar with the experience, especially when it comes to doubles luge. Sliding is like riding a roller coaster with your eyes closed, except you're not connected to a track and are free to navigate your own path. You aren't strapped in and done correctly, it's comparable to walking a tight rope. Doubles luge is twice as difficult because two sliders are trying to work as one to stay on the wire. It's exciting and challenging especially since the slightest human error can drastically change a run.
The top driver does a majority of the steering, while the back driver is responsible for making the run smooth and assisting with difficult turns. Before each run, doubles teammates review every curve on the track and agree on the best approach. It's a constant learning process that is ever evolving and make no mistake, it takes years of practice and repetition for a doubles team to "learn" to maneuver the sled down the track as one.
