The act of jacking off from start to finish while passing through the westbound Eisenhower Tunnel or eastbound Johnson Tunnel. The tunnels are located along Interstate 70 high in the Colorado Rocky Mountains. The tunnels deeply penetrate the hard mountain rock in order to cross the continental divide. The tunnels are just long enough to make jacking off feasible but are far too short for the experience to be enjoyable. Male travelers frequently pitch a pants tent involuntarily while making the voyage due to the altitude. This can be used to the participant’s advantage.

Female travelers may also participate by Jilling their way through the dimly lit tunnel. It is uncertain if any attempt have been made at this time.

There is debate whether team plays are allowed or if it is a solitary activity. Similarly, some still believe that the challenge is not completed unless the jacking or jilling is done while operating the vehicle.
A.A.ron: I finally did it!

Lee-yah: did what?

A.A.ron: the Eisenhower tunnel challenge! Had to stop in Silverthorne to get the mess off my steering wheel and then get some new Nikes!

Lee-yah: OMG that’s great! But weren’t you driving with your mom and grandma???
